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.
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPGetOperatorsSet(KSP ksp, PetscBool *mat, PetscBool *pmat)
Not Collective, though the results on all processes should be the same
Input Parameter#
ksp - the
KSPcontext
Output Parameters#
mat - the matrix associated with the linear system was set
pmat - matrix associated with the preconditioner was set, usually the same as
mat
Note#
This routine exists because if you call KSPGetOperators() on a KSP that does not yet have operators they are
automatically created in the call.
