Then WHY post in a C forum???

He means, the code Dianecht suggested was in FORTRAN.

I don't think that should be a problem in terms of getting it to work with C code, but I understand not wanting to try.

I would recommend taking a peek at the GSL (GNU Scientific Library) but don't get your hopes up as I'm not sure it includes sparse matrix functions. There is another major free software mathematical project I came across on one occasion, but I forget the name ... :-(

I apologize for the earlier Post. I plead lack of sleep or some other form of diminished capacity for my misunderstanding.
