#include "petscmesh.h" PetscErrorCode PETSCDM_DLLEXPORT MeshGetMatrix(Mesh mesh, MatType mtype, Mat *J)Collective on Mesh
mesh | - the mesh object | |
mtype | - Supported types are MATSEQAIJ, MATMPIAIJ, MATSEQBAIJ, MATMPIBAIJ, MATSEQSBAIJ, MATMPISBAIJ, or any type which inherits from one of these (such as MATAIJ, MATLUSOL, etc.). |
Notes: This properly preallocates the number of nonzeros in the sparse matrix so you do not need to do it yourself.
