# PEPMonitorRegisterFn

A function prototype for functions provided to `PEPMonitorRegister()`.

## Synopsis

    PETSC_EXTERN_TYPEDEF typedef PetscErrorCode PEPMonitorRegisterFn(PEP pep,PetscInt its,PetscInt nconv,PetscScalar eigr[],PetscScalar eigi[],PetscReal errest[],PetscInt nest,PetscViewerAndFormat *ctx);

## Calling Sequence

- pep - the polynomial eigensolver context

- its - iteration number

- nconv - number of converged eigenpairs

- eigr - real part of the eigenvalues

- eigi - imaginary part of the eigenvalues

- errest - relative error estimates for each eigenpair

- nest - number of error estimates

- ctx - `PetscViewerAndFormat` object

## Note

This is a `PEPMonitorFn` specialized for a context of `PetscViewerAndFormat`.
