To change the format of the output call <A HREF="https://petsc.org/release/manualpages/Viewer/PetscViewerPushFormat.html#PetscViewerPushFormat">PetscViewerPushFormat</A>(viewer,format) before
this call. Use <A HREF="https://petsc.org/release/manualpages/Viewer/PetscViewerFormat.html#PetscViewerFormat">PETSC_VIEWER_DEFAULT</A> for the default, use <A HREF="https://petsc.org/release/manualpages/Viewer/PetscViewerFormat.html#PetscViewerFormat">PETSC_VIEWER_FAILED</A> to only
display a reason if it fails. The latter can be set in the command line with
-nep_converged_reason ::failed
