# DMKSPSetComputeInitialGuess

set KSP initial guess evaluation function

### Synopsis

    #include "petscksp.h"
    PetscErrorCode DMKSPSetComputeInitialGuess(DM dm,PetscErrorCode (*func)(KSP,Vec,void*),void *ctx)

### Input Argument

| dm | - DM to be used with KSP
| func | - initial guess evaluation function, see KSPSetComputeInitialGuess() for calling sequence
| ctx | - context for right hand side evaluation

### Note

KSPSetComputeInitialGuess() is normally used, but it calls this function internally because the user context is actually associated with the DM.
