# PCGalerkinGetKSP
Gets the `KSP` object in the `PCGALERKIN`
## Synopsis
```
#include "petscksp.h"
PetscErrorCode PCGalerkinGetKSP(PC pc, KSP *ksp)
```
Not Collective
## Input Parameter
- ***pc -*** the preconditioner context
## Output Parameter
- ***ksp -*** the `KSP` object
## Note
Once you have called this routine you can call `KSPSetOperators()` on the resulting ksp to provide the operator for the Galerkin problem,
an alternative is to use `PCGalerkinSetComputeSubmatrix()` to provide a routine that computes the submatrix as needed.
