MatRestoreRowIJ#
Call after you are completed with the ia,ja indices obtained with MatGetRowIJ().
Synopsis#
#include "petscmat.h"
PetscErrorCode MatRestoreRowIJ(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_TRUEorPETSC_FALSEindicating the matrix data structure should be symmetrizedinodecompressed -
PETSC_TRUEorPETSC_FALSEindicating if the nonzero structure of the inodes or the nonzero elements is wanted. ForMATBAIJmatrices the compressed version is always used.n - size of (possibly compressed) matrix
ia - the row pointers
ja - the column indices
Output Parameter#
done -
PETSC_TRUEorPETSC_FALSEindicated that the values have been returned
Note#
This routine zeros out n, ia, and ja. This is to prevent accidental
us of the array after it has been restored. If you pass NULL, it will
not zero the pointers. Use of ia or ja after MatRestoreRowIJ() is invalid.
Fortran Note#
MatRestoreRowIJ() Fortran binding is deprecated (since PETSc 3.19), use MatRestoreRowIJF90()
