I would also suggest some online learning resources to get you started. The following is a mooc taught by UTAustin: https://www.edx.org/course/utaustinx/utaustinx-ut-5-01x-linear-algebra-1162#.U4Es3PldU28

Here's one on Coursera taught by Brown Uni: https://www.coursera.org/course/matrix

I just started the first one and it seems pretty cool! It teaches you Linear Algebra using Python so it's easier to learn. I landed on this thread because I was looking for Linear Algebra learning resources; so I thought I'd spread the word too!
