EPSMonitorAllDrawLG#
Plots the error estimate of all unconverged approximations at each iteration of the eigensolver.

PetscErrorCode EPSMonitorAllDrawLG(EPS eps,PetscInt its,PetscInt nconv,PetscScalar eigr[],PetscScalar eigi[],PetscReal errest[],PetscInt nest,PetscViewerAndFormat *vf)
Collective
Input Parameters#
eps - the linear eigensolver context
its - iteration number
nconv - number of converged eigenpairs so far
eigr - real part of the eigenvalues
eigi - imaginary part of the eigenvalues
errest - error estimates
nest - number of error estimates to display
vf - viewer and format for monitoring

EPSMonitorAllDrawLG()
Notes#
This is not called directly by users, rather one calls EPSMonitorSet(), with this
function as an argument, to cause the monitor to be used during the EPS solve.
Call EPSMonitorAllDrawLGCreate() to create the context used with this monitor.
