It's not a complete book, but the topics it covers are well explained.

Maybe the fact it is concise is a feature—you can quickly get an overview of each topic, without all the details a textbook author would have to cover...

Here is a related concept map of all linear algebra topics, for anyone who is planning to self-study this subject: https://minireference.com/static/conceptmaps/linear_algebra_...

Looks like this uses Flash (SWF) for interactive diagrams. Luckily ruffle.rs [1] works.

Wow nice!

I thought SWF players were impossible, but this clearly proves me wrong!

Another free one (and my favorite) is Sheldon Axler's, who recently open-licensed it,

There's also a large number of HN threads on the topic of "linear algebra books",

There is no royal road to mathematics. All this fuss over finding the best book is an excuse to avoid doing the work of study and practice.

There are certainly writers that are better communicators and give more detail to make it easier to learn while you are practicing and studying. I have had good and bad textbooks in my academic career. So it does not hurt to get recommendations.

One of the most infuriating things about mathematics—for the beginner to a topic—are the assumptions of notation, which you’re meant to know beforehand.
