# 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`. 
## Synopsis
```
#include "petscksp.h" 
PetscErrorCode PCGetOperatorsSet(PC pc, PetscBool *mat, PetscBool *pmat)
```
Not Collective, though the results on all processes should be the same


## Input Parameter

- ***pc -*** the preconditioner context



## Output Parameters

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