Matrix Division

[wiland]

There is a MATMUL function in v.6.0 of the Fortran compiler that can be used to multiply two matrices. Is there any function that allows one to divide two matrices?

There is not a matrix division intrinsic. If you can find a matrix inversion routine, you can multiply by the inverse to perform division.

Hi

I have a similar problem. I want to be able to invert a matrix so in order to conduct matyrix division. Is there any command that can do matrix inversion in the compiler

thanks in advance

There's no Fortran command to invert a matrix, but there's a subroutine included in IMSL that comes with the Professional edition of CVF. If you don't have it, there's free software available on the net that will do it. However, you should realize that matrix inversion can sometimes be tricky: some matrices to not have inverses.
