PETSc version 3.15.5
MatRestoreColumnIJ
Call after you are completed with the ia,ja indices obtained with MatGetColumnIJ().
Synopsis
#include "petscmat.h"
PetscErrorCode MatRestoreColumnIJ(Mat mat,PetscInt shift,PetscBool symmetric,PetscBool inodecompressed,PetscInt *n,const PetscInt *ia[],const PetscInt *ja[],PetscBool *done)
Collective on Mat
Input Parameters
| mat | - the matrix
|
| shift | - 1 or zero indicating we want the indices starting at 0 or 1
|
| symmetric | - PETSC_TRUE or PETSC_FALSE indicating the matrix data structure should be
symmetrized
|
| inodecompressed | - PETSC_TRUE or PETSC_FALSE indicating if the nonzero structure of the
inodes or the nonzero elements is wanted. For BAIJ matrices the compressed version is
always used.
|
Output Parameters
| n | - size of (possibly compressed) matrix
|
| ia | - the column pointers
|
| ja | - the row indices
|
| done | - PETSC_TRUE or PETSC_FALSE indicated that the values have been returned
