Course Overview

Linear algebra may well be the most accessible of all routes into higher mathematics. It requires little more than a foundation in algebra and geometry, yet it supplies powerful tools for solving problems in subjects as diverse as computer science and chemistry, business and biology, engineering and economics, and physics and statistics, to name just a few. Furthermore, linear algebra is the gateway to almost any advanced mathematics course. Calculus, abstract algebra, real analysis, topology, number theory, and many other fields make extensive use of the central concepts of linear algebra: vector spaces and linear transformations.

Mastering Linear Algebra: An Introduction with Applications is the ideal starting point for this influential branch of mathematics, surveying the traditional topics of a first-semester college course in linear algebra through 24 rigorous half-hour lectures taught by Professor Francis Su of Harvey Mudd College. A multi-award-winning math educator, Professor Su was named “the mathematician who will make you fall in love with numbers” by WIRED magazine.

Linear algebra provides insights into complex phenomena that are part of our daily lives, making them less mysterious and showing the astonishing reach of mathematics in areas such as:

  • Computer Graphics: The field of 3-D computer graphics exists because of linear algebra, which transforms shapes in 3-dimensional space by matrix multiplication.
  • GPS: A Global Positioning Satellite (GPS) receiver, such as a smartphone, determines its position based on time signals from several satellites. Linear algebra shows how to take this seemingly complicated problem and make it accessible.
  • Search Engines: The ability to find information quickly on the internet is a key feature of modern life, and it’s made possible by linear algebra, which keeps track of which nodes on a network are linked, and highlights structures that enable the ranking of important web pages.
  • Recommender Systems: Most of us have experienced websites that seem to know more about our tastes than our own family members. The ability of linear algebra to reveal hidden structures lies behind many of these recommender systems.

Indeed, linear algebra has become so central to our modern data-driven world that more and more educators believe the subject should be introduced earlier in the mathematics curriculum. Linear algebra has spawned truly subtle and sophisticated problem-solving strategies that are favored by specialists, but the underlying concepts are relatively simple and within reach of anyone with a firm grasp of algebra and some analytic geometry. (A background in calculus is helpful, but not required.)

In Mastering Linear Algebra, Professor Su puts a premium on visualizing both the results and the reasoning behind important ideas in linear algebra, giving a geometric picture of how to understand matrices and linear equations. Focusing on a wide range of interesting applications, he works through problems step by step, introducing key ideas along the way, starting with:

  • Vectors and vector spaces,
  • Dot products and cross products,
  • Matrix operations, and
  • Linear transformations and systems of linear equations.

Armed with these essential concepts, you dig deeper into properties and problem-solving strategies involving:

  • Bases and determinants,
  • Eigenvectors and eigenvalues,
  • Orthogonality,
  • Markov chains, and much more.

What Is Linear Algebra?

While the term “linear algebra” may evoke a stark image of straight lines and the manipulation of symbols, the subject is far more elegant than that. The “linear” part refers to linear systems of equations and their geometric manifestations as planes or hyperplanes. In such equations, polynomials with exponents and other nonlinear terms are not present. This makes dealing with equations pleasingly straightforward.

Vectors enter the picture because the linear equations can be viewed as a transformation of one vector into another. And the matrices are arrays of numbers that are the coefficients of these linear equations. The “algebra” part of linear algebra is simply the rules for performing operations on the vectors and matrices. From these basic ideas, a vibrant mathematical universe emerges—a rich interplay between algebra and geometry, between computation and visualization, between the concrete and the abstract, and between utility and beauty.

In the very beginning, Professor Su introduces four themes that you encounter throughout the course:

  • Linearity is a fundamental idea in mathematics and in the world. The idea of linearity arises everywhere—from adapting a recipe to calculating the age of the universe. In linear algebra, this property is embodied by linear transformations, which are functions that change one vector in a vector space into another.
  • To understand nonlinear things, we approximate them by linear things. Many phenomena are nonlinear (think of the motion of planets around the sun), but at small scales they are approximately linear. This idea is the heart of calculus, which uses ideas from linear algebra to approximate nonlinear functions by linear ones.
  • Linear algebra reveals hidden structures that are beautiful and useful. Much of what linear algebra does is uncover hidden structures that give insight into what is really going on in a problem, allowing it to be solved with surprising ease. Seeing these unexpected connections and shortcuts can be an aesthetic experience.
  • Linear algebra’s power often comes from the interplay between geometry and algebra. The effectiveness of linear algebra is due in large part to the way problems can be envisioned in both geometric and algebraic terms. The geometric picture feeds intuition about what a solution might look like, while the algebraic tools show the way to an answer.

Big Data, Tamed

Anyone excited about diving into the vast sea of data made possible by the internet and today’s nearly limitless computing power should definitely study linear algebra. Professor Su covers the math behind several techniques that both tame and exploit big data. Early on, he spotlights the problem of error detection, which is used to identify and correct corrupted computer bits. Then later, he zeroes in on the tricks used to encode data as efficiently as possible—in this case, the JPEG image-compression algorithm. In a look at singular value decomposition, he presents another method of data compression. And, Professor Su considers the challenges of search engines and speech recognition programs, explaining how Markov chains model the probability of what to expect given the current state of a system.

Mastering Linear Algebra also briefly introduces you to quantum mechanics, the notoriously baffling theory of subatomic particles. Since quantum theory is written in the language of vectors and matrices, you need linear algebra to understand it. Professor Su provides a taste of that understanding by showing how the apparently paradoxical superposition of states—in which quantum entities can be in two states at the same time—makes perfect sense when you think of it in terms of linear algebra (specifically, as a linear combination of states in a vector space). You learn this fascinating lesson in Lecture 3—by which point you will already be looking at the world in a whole new way.

    Linear Algebra: Powerful Transformations
    Discover that linear algebra is a powerful tool that combines the insights of geometry and algebra. Focus on its central idea of linear transformations, which are functions that are algebraically very simple and that change a space geometrically in modest ways, such as taking parallel lines to parallel lines. Survey the diverse linear phenomena that can be analyzed this way. x
  • 2
    Vectors: Describing Space and Motion
    Professor Su poses a handwriting recognition problem as an introduction to vectors, the basic objects of study in linear algebra. Learn how to define a vector, as well as how to add and multiply them, both algebraically and geometrically. Also see vectors as more general objects that apply to a wide range of situations that may not, at first, look like arrows or ordered collections of real numbers. x
  • 3
    Linear Geometry: Dots and Crosses
    Even at this stage of the course, the concepts you've encountered give insight into the strange behavior of matter in the quantum realm. Get a glimpse of this connection by learning two standard operations on vectors: dot products and cross products. The dot product of two vectors is a scalar, with magnitude only. The cross product of two vectors is a vector, with both magnitude and direction. x
  • 4
    Matrix Operations
    Use the problem of creating an error-correcting computer code to explore the versatile language of matrix operations. A matrix is a rectangular array of numbers whose rows and columns can be thought of as vectors. Learn matrix notation and the rules for matrix arithmetic. Then see how these concepts help you determine if a digital signal has been corrupted and, if so, how to fix it. x
  • 5
    Linear Transformations
    Dig deeper into linear transformations to find out how they are closely tied to matrix multiplication. Computer graphics is a perfect example of the use of linear transformations. Define a linear transformation and study properties that follow from this definition, especially as they relate to matrices. Close by exploring advanced computer graphic techniques for dealing with perspective in images. x
  • 6
    Systems of Linear Equations
    One powerful application of linear algebra is for solving systems of linear equations, which arise in many different disciplines. One example: balancing chemical equations. Study the general features of any system of linear equations, then focus on the Gaussian elimination method of solution, named after the German mathematician Carl Friedrich Gauss, but also discovered in ancient China. x
  • 7
    Reduced Row Echelon Form
    Consider how signals from four GPS satellites can be used to calculate a phone's location, given the positions of the satellites and the times for the four signals to reach the phone. In the process, discover a systematic way to use row operations to put a matrix into reduced row echelon form, a special form that lets you solve any system of linear equations, and tells you a lot about the solutions. x
  • 8
    Span and Linear Dependence
    Determine whether eggs and oatmeal alone can satisfy goals for obtaining three types of nutrients. Learn about the span of a set of vectors, which is the set of all linear combination of those vectors; and linear dependence, where one vector can be written as a linear combination of two others. Along the way, develop your intuition for seeing possible solutions to problems in linear algebra. x
  • 9
    Subspaces: Special Subsets to Look For
    Delve into special subspaces of a matrix: the null space, row space, and column space. Use these to understand the economics of making croissants and donuts for a specified price, drawing on three ingredients with changing costs. As in the previous lecture, move back and forth between a matrix equation, a system of equations, and a vector equation, which all represent the same thing. x
  • 10
    Bases: Basic Building Blocks
    Using the example of digital compression of images, explore the basis of a vector space. This is a subset of vectors that, in the case of compression formats like JPEG, preserve crucial information while dispensing with extraneous data. Discover how to find a basis for a column space, row space, and null space. Also make geometric observations about these important structures. x
  • 11
    Invertible Matrices: Undoing What You Did
    Now turn to engineering, a fertile field for linear algebra. Put yourself in the shoes of a bridge designer, faced with determining the maximum force that a bridge can take for a given deflection vector. This involves the inverse of a matrix. Explore techniques for determining if an inverse matrix exists and then calculating it. Also learn proofs about properties of matrices and their inverses. x
  • 12
    The Invertible Matrix Theorem
    Use linear algebra to analyze one of the games on the popular electronic toy Merlin from the 1970s. This leads you deeper into the nature of the inverse of a matrix, showing why invertibility is such an important idea. Learn about the fundamental theorem of invertible matrices, which provides a key to understanding properties you can infer from matrices that either have or don't have an inverse. x
  • 13
    Determinants: Numbers That Say a Lot
    Study the determinant-the factor by which a region of space increases or decreases after a matrix transformation. If the determinant is negative, then the space has been mirror-reversed. Probe other properties of the determinant, including its use in multivariable calculus for computing the volume of a parallelepiped, which is a three-dimensional figure whose faces are parallelograms. x
  • 14
    Eigenstuff: Revealing Hidden Structure
    Dive into eigenvectors, which are a special class of vectors that don't change direction under a given linear transformation. The scaling factor of an eigenvector is the eigenvalue. These seemingly incidental properties turn out to be of enormous importance in linear algebra. Get started with eigenstuff" by pondering a problem in population modeling, featuring foxes and their prey, rabbits." x
  • 15
    Eigenvectors and Eigenvalues: Geometry
    Continue your study from the previous lecture by exploring the geometric properties of eigenvectors and eigenvalues, gaining an intuitive sense of the hidden structure they reveal. Learn how to calculate eigenvalues and eigenvectors; and for vectors that are not eigenvectors, discover that if you have a basis of eigenvectors, then it's easy to see how a transformation moves every other point. x
  • 16
    In this third lecture on eigenvectors, examine conditions under which a change in basis results in a basis of eigenvectors, which makes computation with matrices very easy. Discover the property called diagonalizability, and prove that being diagonalizable is the equivalent to having a basis of eigenvectors. Also explore the connection between the eigenvalues of a matrix and its determinant. x
  • 17
    Population Dynamics: Foxes and Rabbits
    Return to the problem of modeling the population dynamics of foxes and rabbits from Lecture 14, drawing on your knowledge of eigenvectors to analyze different scenarios. First, express the predation relationship in matrix notation. Then, experiment with different values for the predation factor, looking for the optimum ratio of foxes to rabbits to ensure that both populations remain stable. x
  • 18
    Differential Equations: New Applications
    Professor Su walks you through the application of matrices in differential equations, assuming for just this lecture that you know a little calculus. The first problem involves the population ratios of rats and mice. Next, investigate the motion of a spring, using linear algebra to simplify second order differential equations into first order differential equations-a handy simplification. x
  • 19
    Orthogonality: Squaring Things Up
    In mathematics, orthogonal" means at right angles. Difficult operations become simpler when orthogonal vectors are involved. Learn how to determine if a matrix is orthogonal and survey the properties that result. Among these, an orthogonal transformation preserves dot products and also angles and lengths. Also, study the Gram-Schmidt process for producing orthogonal vectors." x
  • 20
    Markov Chains: Hopping Around
    The algorithm for the Google search engine is based on viewing websurfing as a Markov chain. So are speech-recognition programs, models for predicting genetic drift, and many other data structures. Investigate this practical tool, which employs probabilistic rules to advance from one state to the next. Find that Markov chains converge on at least one steady-state vector, an eigenvector. x
  • 21
    Multivariable Calculus: Derivative Matrix
    Discover that linear algebra plays a key role in multivariable calculus, also called vector calculus. For those new to calculus, Professor Su covers essential concepts. Then, he shows how multivariable functions can be translated into linear transformations, which you have been studying since the beginning. See how other ideas in multivariable calculus also fall into place, thanks to linear algebra. x
  • 22
    Multilinear Regression: Least Squares
    Witness the wizardry of linear algebra for finding a best-fitting line or best-fitting linear model for data-a problem that arises whenever information is being analyzed. The methods include multiple linear regression and least squares approximation, and can also be used to reverse-engineer an unknown formula that has been applied to data, such as U.S. News and World Report's college rankings. x
  • 23
    Singular Value Decomposition: So Cool
    Next time you respond to a movie, music, or other online recommendation, think of the singular value decomposition (SVD), which is a matrix factorization method used to match your known preferences to similar products. Learn how SVD works, how to compute it, and how its ability to identify relevant attributes makes it an effective data compression tool for subtracting unimportant information. x
  • 24
    General Vector Spaces: More to Explore
    Finish the course by seeing how linear algebra applies more generally than just to vectors in the real coordinate space of n dimensions, which is what you have studied so far. Discover that Fibonacci sequences, with their many applications, can be treated as vector spaces, as can Fourier series, used in waveform analysis. Truly, linear algebra pops up in the most unexpected places! x

Mastering Linear Algebra: An Introduction with Applications is rated 4.4 out of 5 by 47.
Rated 5 out of 5 by from Joy in the journey When I was nearing retirement from my job as an ESL teacher in New York I told my colleagues that I was now going to study math as an audit student at my local community college and that is exactly what I have done. Using the Great Courses video lectures as both a preview and a resource to actual class room instruction has been extremely beneficial to my understanding. Linear Algebra is now my fifth upper level math course that I have enjoyed. I have found the professor to be clear, engaging and able to to convey very complex ideas through a series of analogies and personal stories. Being able to access my courses via my iPad or iPod allows me to listen or watch lectures while walking, sitting at home, driving in my car or during long flights. I can think of no better way to continue my journey as a lifelong learner.

Rated 2 out of 5 by from Read a book instead If you have the discipline to read a math book, I suggest you find a good linear algebra book and just read the book. From my perspective, this guy, Su, sounds exactly like that's what he is doing. Frank

Rated 5 out of 5 by from Excellent Course I had been wanting to do a refresher on Linear Algebra, so I selected this course, taught by Professor Su. I was very, very pleased with the course. Professor Su is an outstanding communicator and his passion for the subject infuses the lectures with interest and energy. This course is not for the “feint of heart” mathematically. The course is loaded with math, as it should be, but the math is not too technically difficult for those competent in Calculus. I would recommend this course unequivocally for those with math training.

Rated 5 out of 5 by from Great insight into linear algebra applications! Great teacher. Very insightful into what I was looking for. I needed to learn to use matrices to help me in calculus, build basic neural nets, and figure out real world engineering problems in a straightforward, simple way; and I found it in this course.

Rated 5 out of 5 by from Great features maybe I got this two weeks ago. I opened the package and have started chapter 1. I am glad I got this, but because I have not really worked through much of the material I have no idea how good it is. However, I keep getting these requests to fill in a survey while the material is fresh in my mind. I'll give it 5 stars to be nice but reserve the right to change my mind at a later date. I hope by answering the survey they will leave me in peace.

Rated 5 out of 5 by from Genuinely helpful Even though technically I had an "advanced" knowledge of the subject prior to starting (I have a PhD in physics), there were inevitable gaps in my understanding. The best parts for me were the relationships the professor made between the algebraic and the geometric. Nicely done sir, and I thank you. The graphics (putting up equations and then highlighting the parts as he talked) was excellent, and much appreciated.

Rated 4 out of 5 by from Just started I love the great courses I have just started this class. I have't even finished the first lesson but I have started it. I expect it to be excellent.
Date published: 2019-12-14
Rated 2 out of 5 by from Requires you to buy a textbook I would like to start by stating that Professor Su does a great job presenting the material. Those considering the course, however, should be aware of a few significant deficits. Unlike The Great Courses calculus courses, the course does not provide meaningful problems to work. The course information recommends buying a text book for that purpose. Unfortunately, this is not a stand alone course. Be aware that you will need other resources. I bought the print course guidebook, and it has some errors in the diagrams and formulas. It also doesn't always use the same examples as in the lecture, and sometimes omits some of the lecture material. Overall, I believe this is a very good qualitative review for those who already know the subject or desire only an overview of the subject, but not suitable for those expecting a stand alone introductory course which has problems to solve. By adding problems to work, step by step solutions, and editing the course book, the course would rate a 5.

Rated 5 out of 5 by from Revealing hidden structures At last my wish come true. Having taking the math courses on algebra and calculus offered by the Teaching Company, it was needed a linear algebra course. This course is excellent; its focus on linear transformations provides a powerful insight to revealing hidden structures. I enjoyed very much the lectures on eigenvalues and eigenvectors, as well as the lectures on the least squares method and Markov chains. In my opinion, this course would be even more complete with a deeper explanation regarding vector projections.

Rated 5 out of 5 by from LINEAR ALGEBRA - good review I actually already knew some linear algebra before watching the course. So I took the course as a review and to see if maybe I had some holes in my knowledge. The review was good (although it seemed a bit slow in places because I already knew a lot of it), and sure enough I did learn several new things. So I'm glad that I watched it.

Rated 5 out of 5 by from Superb course I love this course. It is focused, clear and well organized. Prof. Su with his quite enthusiasm is well organized and provides proofs for all theorems with ease and simplicity and connects the parts of the subject very well. Very fundamental and important subject that is presented in a very effective way more than college courses on the same subject that I have seen. However, his style might not be for everyone as his pace is relatively fast and requires good amount of attention to keep up with him, but if you do, you will really enjoy the course.

Rated 5 out of 5 by from The best Mathematics course from Great Courses I have taken several math courses from Great Courses. Mastering Linear Algebra is probably the best Mathematics that I've taken from them. My undergraduate degree in Mathematics included two linear algebra courses but that was more than 20 years ago. I purchased this course as a review. It has my expectations. To get the most our of this course, be prepared to put in some work beyond listening to the lectures but if you are trying to refresh your knowledge or just get an introduction to linear algebra, then you will be impressed with the results.

Rated 4 out of 5 by from Mixed Feelings There are three critical goals in teaching any math course: First, and foremost, students should leave the course with a deep, intuitive understanding of the material. Secondly, students should become familiar with the many applications associated with the particular math topic. Finally, students should be exposed to the formal mathematical underpinnings of the topic so that they can develop an appreciation of the logical framework upon which it all rests. In my opinion, Dr. Su does an outstanding job of presenting a wide variety of applications associated with Linear Algebra. He also does a fairly good job of reviewing the mathematical framework of Linear Algebra, though he rushed through some of the axioms with little explanation. Where I found his approach lacking was in helping the student develop a deep, intuitive understanding of Linear Algebra, particularly in developing a deep understanding of what a vector truly is---and isn't. I believe Banesh Hoffman, the author of the classic work, "About Vectors", rolled over in his grave when he heard Dr. Su claim that a vector is equivalent to a directed line segment on a graph. Like zippythepinhead below, I don't lay all of the blame for the shortcomings of this course on Dr. Su. The bottom line is that Linear Algebra cannot be taught with any depth in just 12 hours. While Dr. Su bravely attempted to do just that, I believe he was doomed from the outset. I place the blame for the shortcomings of this course squarely on The Great Courses company management. To explain further, like some of the other reviewers, I petitioned The Great Courses customer service people for many years to produce a course on Linear Algebra given its central place in mathematics. Quite frankly, the lack of such a course led me to question the credibility of The Great Courses, especially since they are now cranking out so many non-academic courses in their Better Living category (Knitting, anyone?). I understand that, in the end, they have to offer courses which will sell the most in order to make a profit. At the same time, academic integrity demands that they adequately cover all of the traditional topics of Math and Science. On a more personal note, I wanted badly to love this course for several reasons. As an amateur math junkie, Linear Algebra is my favorite topic given its intriguing connections between algebra and geometry. I usually have more "a-ha" moments when reviewing Linear Algebra than any other topic. In addition, as an alumnus of Harvey Mudd College and an acquaintance of Dr. Benjamin, I was super-excited to see Dr. Su chosen to teach the course. And, finally, I considered it a personal victory when The Great Courses finally gave in and offered a course on Linear Algebra after I called and wrote to them so many times over the past 15 years or so. As such, maybe my disappointment is a little exaggerated. However, since it appears that no more Linear Algebra courses will be offered by The Great Courses after this one, I will just have to do my best to appreciate the hard work Dr. Su put into teaching this course and move on.

Rated 3 out of 5 by from Useful mathematics! I took this course in college and it took a lot of effort. This was one tool that can help. The other tool was Linear Algebra for Dummies. This math class is different from other classes because there is a long vocabulary list to learn. This professor could slow down a bit on the introduction of new vocabulary and maybe type the vocabulary on screen to look at. Words like “subspaces,” “determinant,” “span” and “eigenvalues” can make this stuff appear difficult and confusing.

Rated 4 out of 5 by from So much information, so little time. This is a well executed course with lots of information, but seems unclear of its intent or its targeted audience. In general it attempts to cover too much ground in not enough time. This is definitely a challenging course for both the 1st time student of Linear Algebra, and the intermediate student with some previous education in the subject. Before this course I started with Prof. Micheal Starbird’s ‘Change and Motion:Calculus Made Clear’ and continued through Prof. Bruce Edward’s Precalculus and 3 part Calculus courses. After those I delved into Linear Algebra through various texts and online sources, including Prof. Gilbert Strang’s famous MIT lectures. Yet after all of that, I still found this Linear Algebra course particularly challenging. Prof. Micheal Starbird’s ‘Calculus Made Clear’ functioned more on the level of a survey course answering the question, “What is Calculus?”, While Prof. Bruce Edwards’ Calculus series brilliantly tackled the nuts and bolts of the ’How to’ of calculus. This course falls somewhere in between those 2 approaches. Lectures 1-16 explain the basics of Linear Algebra, while offering some unique insights along the way. After that the lectures take a significant step up in complexity and abstraction. If the first part is too basic for experienced students, the last part is far too advanced for beginners. This may impart some lasting value to the course, permitting the viewer an opportunity to grow into it and continue learning over time, but it somewhat fails both beginner and advanced students in the short term, in that it attempts to cover too much ground without thoroughly developing any particular concept. I don’t mean to imply that the course is a failure or not worthwhile, but it did not live up to my expectations for a complete learning experience, on the level of Prof. Bruce Edwards’ Calculus courses. I guess I was hoping for an ‘end-all, be-all’ solution. The presentation is first rate, and Prof. Su does an excellent job of dispensing the complex information understandably and at a reasonable pace. The on-screen graphics are well designed and clearly visible. The progression of the lectures is well paced and logically ordered, though sometimes feel a bit rushed for the complexity of the ideas. The guidebook provides sufficient reinforcement of the ideas presented in the lectures, with some fresh content of its own. There are a few practice problems for each lecture, but not enough to provide adequate practice to firmly cement the concepts. I’m only awarding 4 stars on the basis that the course attempts to accomplish too much in only 24 lectures. It might be just right for some students, but I wasn’t quite up to the challenge.

Rated 2 out of 5 by from Mastery is not possible here This course is a zip file that needs to be unzipped. Or, as one lecture tries to explain, it is a Jpeg that has eliminated information to its detriment. You cannot master or even appreciate linear algebra in 12 hours. This course runs through a multitude of topics which could be researched somewhere else later but not within the framework of this course. The Great Courses misfired here badly. There is far too much text and lecturing and not nearly enough examples; and even the examples presented are low quality graphics and not helpful. I wish they would let the Professor try again and give him 36 lectures and some feedback/support along the way.

Rated 5 out of 5 by from Course title sums it up. The course covers a wide variety of topics with sufficient in-depth analysis. Most of your subscribers likes to keep the courses simple and easy to understand. I prefer courses to be more difficult as it requires more thought and a deeper understanding of principles and theory. Keep up the great work.

Rated 5 out of 5 by from Dr Su has such a mastery of mathematics! I was very excited to see the Great Courses add this class - (it's been a long time waiting!) and even more impressed with the professor. I love it when The Great Courses does "real" classes where you are learning a subject for real, not just in a layman's way or entertaining way. This is the real deal.

Rated 5 out of 5 by from Great course. This is truly an outstanding course. It is interesting. Professor Su's lectures are clear, and the graphics are excellent. The course notes are very good. It would be great if the Teaching Company provided more math courses on this level. Thanks for doing this.

Rated 2 out of 5 by from A lot of theory, few useful applications I didn't know what linear algebra was before buying this course. Had I known that it has a lot to do with the operations that are performed by computers to enable computer graphics, I would not have bought it. Frankly, I don't care how the computer does it. But I do like mathematics, and found the material interesting enough to plow through all the lectures. Two stars.

Rated 5 out of 5 by from Linear Algebra is so cool I finished this course just now (video) and I have to say it's amazing what can be done in 30 minutes. Prof Su is a master and I found the presentation and material excellent review. Also, the improvements in the course guidebook are definitely worth crowing about, usability is much increased. I thoroughly enjoyed the sections on eigen stuff and SVD; maybe a little more on Fourier Analysis would be nice and even a little deeper look at the complex number aspects. Bottom line, I definitely recommend this video course for someone with a first course Calculus experience.

Rated 5 out of 5 by from Meets the challenge of a tough subject Superb instructor! Detailed and fast-moving. Your prior math knowledge should be fairly up-to-date. One of the best of many Great (Math) Courses I have bought.

Rated 5 out of 5 by from For those who are serious about the subject An excellent introduction, provided you are serious about learning linear algebra--equations and all. All Great Courses cover interesting subjects, but some are light entertainment while others provide a genuine university-level treatment. This course falls into the latter category. Be prepared to pay full attention and have one hand ready to pause and rewind, while the other grips pencil and paper.
