Not Collective, but the SNES and KSP objects must live on the same MPI_Comm

### Input Parameters

| snes | - the SNES context
| ksp | - the KSP context

### Notes

The SNES object already has its KSP object, you can obtain with SNESGetKSP() so this routine is rarely needed.

The KSP object that is already in the SNES object has its reference count decreased by one.
