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_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 MATBAIJ 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
