KSPGetOperatorsSet

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

#include "petscksp.h" 
PetscErrorCode  KSPGetOperatorsSet(KSP ksp,PetscBool  *mat,PetscBool  *pmat)

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

pc -the KSP context

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

KSP, get, operators, matrix, linear system
