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
Input Parameters#
- mat - the matrix 
- shift - 1 or zero indicating we want the indices starting at 0 or 1 
- symmetric - - PETSC_TRUEor- PETSC_FALSEindicating the matrix data structure should be symmetrized
- inodecompressed - - PETSC_TRUEor- PETSC_FALSEindicating if the nonzero structure of the inodes or the nonzero elements is wanted. For- MATBAIJmatrices the compressed version is always used.
Output Parameters#
- n - size of (possibly compressed) matrix 
- ia - the column pointers 
- ja - the row indices 
- done - - PETSC_TRUEor- PETSC_FALSEindicated that the values have been returned
