# PCFactorSetUpMatSolverType
Can be called after `KSPSetOperators()` or `PCSetOperators()`, causes `MatGetFactor()` to be called so then one may set the options for that particular factorization object. 
## Synopsis
```
#include "petscpc.h" 
PetscErrorCode PCFactorSetUpMatSolverType(PC pc)
```

## Input Parameter

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



## Note
After you have called this function (which has to be after the `KSPSetOperators()` or `PCSetOperators()`) you can call `PCFactorGetMatrix()` and then set factor options on that matrix.
