Need matrix inversion C routine.

[Wm. Keith Brummett]

    I have need of a small, fast routine in C language that will invert
    matrices of order <= 4.  (Actually, I'll take a large, slow one that
    does order 2 or 3).  Does anyone have something like this that they
    would care to send me?  If it matters, it will be used in a small
    graphics project.

    BTW, can anyone tell me why it is that every language except C seems
    to have standard subroutines to do this?

    Thanks in advance!
