Why More Linear Algebra? by David Austin

Bookmarked Why More Linear Algebra? by David Austin (More Linear Algebra)

The main purpose of this blog is to share updates about the open-access, open-source textbook Understanding Linear Algebra. Though work is continuing on this project, the HTML version of the text is now freely available, the forthcoming PDF version will also be free, and low-cost print options will be provided. The PreTeXt source code will be posted on GitHub as well.
