  PetscObjectGetType - Gets the object type of any `PetscObject`.

  Not Collective

  Input Parameter:
. obj - any PETSc object, for example a `Vec`, `Mat` or `KSP`. It must be cast with a (`PetscObject`), for example,
        `PetscObjectGetType`((`PetscObject`)mat,&type);

  Output Parameter:
. type - the object type, for example, `MATSEQAIJ`

  Level: advanced
