Hi, In MatCreateMPIAIJ() function, it needs d_nz, d_nnz[], o_nz, o_nnz[]. If one has a MATAIJ matrix, how to obtian this information? thanks a lot.
PetscErrorCode PETSCMAT_DLLEXPORT MatCreateMPIAIJ(MPI_Comm comm,PetscInt m,PetscInt n,PetscInt M,PetscInt N,PetscInt d_nz,const PetscInt d_nnz[],PetscInt o_nz,const PetscInt o_nnz[],Mat *A) Regards, Yujie -------------- next part -------------- An HTML attachment was scrubbed...
