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 Many br

Input Parameters

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

Output Parameters

n - size of (possibly compressed) matrix Many br
ia - the column pointers Many br
ja - the row indices Many br
done - PETSC_TRUE or PETSC_FALSE indicated that the values have been returned Many br
