    Allen Downey (author of the above) has a number of books on computer science-y things. You can buy hardcopies but I think all of them are also just freely available.

    Here's a few:

    Matrix multiplication introduced before vector addition... the "Linear Algebra Done Right" in me is screaming inside.

    That being said, it is definitely cool to have a Jupyter-notebook based set of examples of practical linear algebra

      And eigenvectors in the first lesson!

        I think at the beginning of learning LA I would have benefited from a more broad introduction to the topic by explaining that it is the algebra of transformations, generally linear transformations, and also the art of quantifying those transformations in meaningful ways.

        I would have benefited from some more handwaving in this regard (matrix multiplication, eigenvectors and eigenvalues) and less on the mechanics of the operations, before starting on the basic technicalities. But a “lesson” on these topics on day 0 is too soon

    Linear Algebra is dope, as in when we got to apply some mid-level linear to a real business problem and it worked i got high

    I got my hands on a stanford Math 55 textbook and tried to do the exercises in numpy.
