Collective on Mat

	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

	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
