# 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

### 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
| done | - PETSC_TRUE or PETSC_FALSE indicated that the values have been returned
