Linear algebra *is* boring. I hate to admit it, but the reasons why I
got
interested, was that a fellow student of mine at college, who didn't
exactly
excel in maths, developed an interest in linear algebra and talked very

fondly about it. I got curious about what this guy had seen that I had
missed and took an extra intro class on linear algebra when I went to
university. That, along with matlab becoming available to me, basically

made it a no-brainer to start learning linear algebra.

After that, I used linear algebra in my MSc thesis basically to save on

writing efforts (a matrix equation is WAY easier to write than a
triple-
nested sum), as well as ease of programming (what can be written
as a matrix equation can be written almost directly as matlab code).

Heh, I started using linear algebra out of blows to my pride, and stuck

with it out of a highly developed sense of laziness...

Oh well.

Thank you very much!
