| section | - The PetscSection describing the range of the constraint matrix: relates rows of the constraint matrix to dofs of the default section. Returns NULL if there are no local constraints. | |
| mat | - The Mat that interpolates local constraints: its width should be the layout size of the default section. Returns NULL if there are no local constraints. |
Note: This gets borrowed references, so the user should not destroy the PetscSection or the Mat.
