I switched the arguments to CALL MatXAIJSetPreallocation(Ap,1,0,dnnz,0,onnz,PETSC_NULL_OBJECT,PETSC_NULL_OBJECT,ierr)
but it doesn't seem to like that; [0]PETSC ERROR: MatSetValues() line 1075 in /home/jmousel/NumericalLibraries/petsc-hg/src/mat/interface/matrix.c [0]PETSC ERROR: --------------------- Error Message ------------------------------------ [0]PETSC ERROR: Object is in wrong state! [0]PETSC ERROR: Must call MatXXXSetPreallocation() or MatSetUp() on argument 1 "mat" before MatSetValues()!
