    PetscErrorCode PETSCMAT_DLLEXPORT MatGetRowIJ(Mat mat,PetscInt shift,PetscTruth symmetric,PetscInt *n,PetscInt *ia[],PetscInt* ja[],PetscTruth *done)

Collective on Mat

### Input Parameters

| mat | - the matrix
| shift | - 0 or 1 indicating we want the indices starting at 0 or 1
| symmetric | - PETSC_TRUE or PETSC_FALSE indicating the matrix data structure should be symmetrized

### Output Parameters

| n | - number of rows in the (possibly compressed) matrix
| ia | - the row pointers
| ja | - the column indices
| done | - PETSC_TRUE or PETSC_FALSE, indicating whether the values have been returned
