A First Course in Linear Algebra (A Free Textbook)

[Owen Densmore]

Well, while reading on eigenvalues in an algorithms text, I thought  
I'd re-read on the topic.  From wikipedia I ended up here:
   http://linear.ups.edu/

Its not at all bad, is downloadable for free, and has a LuLu paper  
version.  Not only a fascinating book, but the website has interesting  
pointers to other free math books and more.

Hmm..this might also be of interest to sfComplex as a way to publish  
material that comes from that effort.
