KSPMonitorSolution
Monitors progress of the KSP solvers by calling VecView() for the approximate solution at each iteration.
Synopsis
#include "petscksp.h"
PetscErrorCode KSPMonitorSolution(KSP ksp,PetscInt its,PetscReal fgnorm,PetscViewerAndFormat *dummy)
Collective on KSP
Input Parameters
| ksp | - the KSP context
|
| its | - iteration number
|
| fgnorm | - 2-norm of residual (or gradient)
|
| dummy | - a viewer
|
Notes
For some Krylov methods such as GMRES constructing the solution at
each iteration is expensive, hence using this will slow the code.
