# PCFactorGetMatrix
Gets the factored matrix from the preconditioner context. This routine is valid only for the `PCLU`, `PCILU`, `PCCHOLESKY`, and `PCICC` methods.
## Synopsis
```
#include "petscksp.h"
PetscErrorCode PCFactorGetMatrix(PC pc, Mat *mat)
```
Not Collective though mat is parallel if pc is parallel
## Input Parameter
- ***pc -*** the preconditioner context
## Output parameters
- ***mat -*** the factored matrix
## Note
Does not increase the reference count for the matrix so DO NOT destroy it
