Not Collective

## Input Parameters

- obj - a PETSc object, for example a `Vec`, `Mat` or `KSP`. It must be cast with a (`PetscObject`), for example, `PetscObjectBaseTypeCompareAny`((`PetscObject`)mat,…);

- type_name - one or more string arguments containing type names, pass the empty string “” as the last argument
