Collective
Input Parameters#
nep - the nonlinear 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

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