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
Input Parameters#
func - right hand side evaluation function, for calling sequence see
KSPSetComputeRHS()ctx - context for right hand side evaluation
Note#
KSPSetComputeRHS() is normally used, but it calls this function internally because the user context is actually
associated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or
not.
Developer Note#
If DM took a more central role at some later date, this could become the primary method of setting the matrix.
