SVDMonitorConvergedDrawLG#

Plots the number of converged eigenvalues at each iteration of the singular value solver.

Synopsis#

#include "slepcsvd.h" 
PetscErrorCode SVDMonitorConvergedDrawLG(SVD svd,PetscInt its,PetscInt nconv,PetscReal sigma[],PetscReal errest[],PetscInt nest,PetscViewerAndFormat *vf)

Collective

Input Parameters#

svd - the singular value solver context
its - iteration number
nconv - number of converged singular triplets so far
sigma - singular values
errest - error estimates
nest - number of error estimates to display
vf - viewer and format for monitoring

Options Database Key#

-svd_monitor_conv draw::draw_lg - activates SVDMonitorConvergedDrawLG()

Notes#

This is not called directly by users, rather one calls SVDMonitorSet(), with this function as an argument, to cause the monitor to be used during the SVD solve.

Call SVDMonitorConvergedDrawLGCreate() to create the context used with this monitor.
