Dear all, I'm using Petsc 2.3.1 for my master thesis. I want to solve a linear problem Ax=b in parallel programming using MPICH with complex variables. I can get the A matrix from my fortran code but i can not find in which format i must write it for reading by Petsc. I'm really not familiar with c programming so I'll be happy for a solution in fortran.
THANKS, Evrim
