## Synopsis

    #include "slepcpep.h"
    PetscErrorCode PEPView(PEP pep,PetscViewer viewer)

Collective

## Input Parameters

- pep - the polynomial eigensolver context

- viewer - optional visualization context

## Options Database Key

- -pep_view - calls `PEPView()` at end of `PEPSolve()`

## Notes

The available visualization contexts include

- `PETSC_VIEWER_STDOUT_SELF` - standard output (default)

The user can open an alternative visualization context with `PetscViewerASCIIOpen()` to output to a specified file.
