#include "petscmat.h" PetscErrorCode MatGetColumnIJ(Mat mat,PetscInt shift,PetscBool symmetric,PetscBool inodecompressed,PetscInt *n,const PetscInt *ia[],const PetscInt *ja[],PetscBool *done)Collective on Mat Many br
mat | - the matrix Many br | |
shift | - 1 or zero indicating we want the indices starting at 0 or 1 Many br | |
symmetric | - PETSC_TRUE or PETSC_FALSE indicating the matrix data structure should be Many brsymmetrized Many br | |
inodecompressed | - PETSC_TRUE or PETSC_FALSE indicating if the nonzero structure of the Many brinodes or the nonzero elements is wanted. For BAIJ matrices the compressed version is Many bralways used. Many br | |
n | - number of columns in the (possibly compressed) matrix Many br | |
ia | - the column pointers Many br | |
ja | - the row indices Many br |
