Synopsis
#include "petscksp.h"
PetscErrorCode KSPSetComputeRHS(KSP ksp,PetscErrorCode (*func)(KSP,Vec,void*),void *ctx)
Logically Collective
Input Arguments
| ksp | - the KSP context
|
| func | - function to compute the right hand side
|
| ctx | - optional context
|
Calling sequence of func
func(KSP ksp,Vec b,void *ctx)
| ksp | - the KSP context
|
| b | - right hand side of linear system
|
| ctx | - optional user-provided context
|
Notes
The routine you provide will be called EACH you call KSPSolve() to prepare the new right hand side for that solve
