    Go to LEM.MA/LA for videos, exercises, and to ask us questions directly.

    Of all my time spent online in the last 20 years, watching this lecture series was the most worth while. Thanks professor!

    I loved this content, look forward to going through parts 2 and 3, and bought your book. This sentence from the book really struck a chord with me: "It takes several passes to learn linear algebra to the point that it becomes one of your favorite tools." Indeed. Oh indeed! I remember taking a linear algebra course 30+ years ago and thinking, "This is so simple, it's hard." What I realize now is that it is not the simplicity, it's the abstract nature of linear algebra that makes it challenging. It takes lots and lots of practice and play and thinking and tinkering.

      Congrats! Also, this is just part 1 of a longer series, out of a total of 4. Here's Part 2: ua-cam.com/video/I04GHpKc-WQ/v-deo.html

    I found your channel searching for “matrix inversion lemma”. It’s used in the derivation of the Kalman filter using Bayes’ theorem. Take it from an old retired aerospace engineer: This linear algebra is practical!
    This is a good math instructor. He has a loud clear voice. He writes cleanly and legibly. He is trying to impart knowledge - not just show off his own intelligence.
    I’ve always thought that good handwriting was the least appreciated of skills necessary to be a good mathematician - and I don’t mean for pedagogy.

    Thank you. You gave me a lot better grasp and view about liner algebra. Looking forward to part 2 :).

    I completed part 1. I started from the website but I got some issues from the server by then I followed from here(the place I found the course).Thank you!

      Hey Alekssandro, please let us know what issues you were having with Lemma. Thanks!

      I had trouble with the videos; they simply wouldn't play no matter what, in Chrome, on a Chromebook. I think this is because I have autoplay turned off in Chrome settings. I did find that I could open an incognito window in Chrome, then log in, and videos would play.

    Wouldn't the swap (S) operations generally be interleaved with the L operations? I think you showed only a single S operation after the L operations for the sake of simplicity?

    Dear Sir:
    Wow! Thanks! This is really amazing! This is truly beautiful!
    This video made me curious about the history of Gaussian Elimination and I was surprised to find that Newton first used it in the West but it appears to date back 2,000 years to China:

    People can be so incredibly brilliant.
    Thanks so much for sharing these videos. They are, at times, jaw-dropping!
