DMKSPSetComputeRHS
set KSP right hand side evaluation function
Synopsis
#include "petscksp.h"
PetscErrorCode DMKSPSetComputeRHS(DM dm,PetscErrorCode (*func)(KSP,Vec,void*),void *ctx)
Not Collective Many br
Input Argument
| dm | - DM to be used with KSP Many br |
| func | - right hand side evaluation function, see KSPSetComputeRHS() for calling sequence Many br |
| ctx | - context for right hand side evaluation Many br |
Many br
Note
KSPSetComputeRHS() is normally used, but it calls this function internally because the user context is actually Many brassociated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or Many brnot. If DM took a more central role at some later date, this could become the primary method of setting the matrix. Many br
