# EPSMonitorFn

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

## Synopsis

    PETSC_EXTERN_TYPEDEF typedef PetscErrorCode EPSMonitorFn(EPS eps,PetscInt its,PetscInt nconv,PetscScalar eigr[],PetscScalar eigi[],PetscReal errest[],PetscInt nest,PetscCtx ctx);

## Calling Sequence

- eps - the linear 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 - optional monitoring context, as provided with `EPSMonitorSet()`
