#4It seems like the "github.com" link would be a better and more canonical url rather than link an opaque url to "githubusercontent.com" https://github.com/kenjihiranabe/The-Art-of-Linear-Algebra

#5I like how the author sets up a "grammar of matrix multiplications," and then reuses the same patterns in the rest of the document.
For people who might not be familiar, these visual notes are inspired by and complement Prof. Strang's new book https://math.mit.edu/~gs/everyone/ and course https://ocw.mit.edu/resources/res-18-010-a-2020-vision-of-li... https://www.youtube.com/playlist?list=PLUl4u3cNGP61iQEFiWLE2... see also https://news.ycombinator.com/item?id=23157827

#6Wow this is really well done. It's like a visual-algebraic approach... I've never seen this before.

#7In undergrad, my mnemonic for these operations was visualizing the matrices animated in my head. The more complex ones, it was actually easier for me to remember Scheme functions that represent the algorithm (all expressed via higher-order functions so it was pretty concise); this was unique to my circumstances as an undergrad, not something I can pull off today without reviewing a lot of material.
Presenting the operations with color and blocks just gives a more natural "user interface" (lacking a better term) for remembering it!

#8Also, they say "rank 1 matrix", but they haven't defined the concept of rank yet.
Some readers might find this kind of presentation acceptable, but personally I strongly dislike it when concepts are used before they are defined.

#10On the first page they say "if neither a or b are 0", but they haven't defined what it means for a vector to be 0. Also, they say "rank 1 matrix", but they haven't defined the concept of rank yet. Some readers might find this kind of presentation acceptable, but personally I strongly dislike it when concepts are used before they are defined.
