PCGetOperatorsSet

Determines if the matrix associated with the linear system and possibly a different one associated with the preconditioner have been set in the PC.

#include "petscksp.h" 
PetscErrorCode  PCGetOperatorsSet(PC pc,PetscBool  *mat,PetscBool  *pmat)

Not collective, though the results on all processes should be the same

pc -the preconditioner context

	mat	- the matrix associated with the linear system was set
	pmat	- matrix associated with the preconditioner was set, usually the same

PC, get, operators, matrix, linear system
