KSPMonitorTrueResidualDrawLG#
Plots the true residual norm at each iteration of an iterative solver.
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPMonitorTrueResidualDrawLG(KSP ksp, PetscInt n, PetscReal rnorm, PetscViewerAndFormat *vf)
Collective
Input Parameters#
ksp - iterative context
n - iteration number
rnorm - 2-norm (preconditioned) residual value (may be estimated).
vf - The viewer context
Options Database Key#
-ksp_monitor_true_residual draw::draw_lg - Activates
KSPMonitorTrueResidualDrawLG()
Notes#
This is not called directly by users, rather one calls KSPMonitorSet()
, with this function as an argument, to cause the monitor
to be used during the KSP
solve.
Call KSPMonitorTrueResidualDrawLGCreate()
to create the context needed for this monitor
