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
