Optimized matrix multiplication functions for pascal?:

They are available in a library named LAPACK. You can find downloads

by doing a Google search on this name. It is coded in FORTRAN though.

They are easy to code, as they are simple linear algebra. A good

textbook on linear algebra would be a great help to you.

However, LAPACK gets mighty complicated when it gets into other areas

of numerical linear algebra. If your FORTRAN code uses more

complicated routines, you might find it convenient simply to call the

LAPACK FORTRAN code directly. Maintaining a Pascal version of LAPACK

would be a non-trivial -- even arduous -- task, but you could check the

FPC Wiki to see if somebody might already have done that for you.
