I have a couple of matrix/vector classes that I wrote. The matrix is 4x4
and the vector is 4X1, just like the ones they use in OpenGL. Anyway,
when I wrote it quick and dirty, I used all lists. I just went back and
replaced lists with arrays where I could. Much to my surprise, it was
about half again slower using arrays instead of lists! I thought that
arrays were supposed to be more effecient than lists, but I guess they
aren't. In case it would make a difference, this was done on a 400 MHZ
linux box and python 2.0
Yeah, I know that I should learn NumPy and implement it there, but one
thing at a time.
