# NEPMonitorConverged

Print the approximate values and error estimates as they converge.

## Synopsis

    #include "slepcnep.h"
    PetscErrorCode NEPMonitorConverged(NEP nep,PetscInt its,PetscInt nconv,PetscScalar eigr[],PetscScalar eigi[],PetscReal errest[],PetscInt nest,PetscViewerAndFormat *vf)

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

## Options Database Key

- -nep_monitor_conv - activates `NEPMonitorConverged()`

## Note

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.
