How much time do you have ? You can easily spend several years and get multiple PhDs in linear algebra, but if you only have half an hour to devote to this, I strongly suggest Leduc's Cliff Notes. http://www.amazon.com/Linear-Algebra-Cliffs-Quick-Review/dp/0822053314 http://www.amazon.com/Linear-Algebra-Cliffs-Quick-Review/dp/... Amazing writing, very succint & hacker-friendly.
