# DSNEPSetMinimality

Sets the maximum minimality index used internally by the `DSNEP`.

## Synopsis

    #include "slepcds.h"
    PetscErrorCode DSNEPSetMinimality(DS ds,PetscInt n)

Logically Collective

## Input Parameters

- ds - the direct solver context

- n - the maximum minimality index

## Options Database Key

- -ds_nep_minimality <n> - sets the maximum minimality index

## Notes

The maximum minimality index is used only in the contour integral method, and is related to the highest moments used in the method. The default value is 1, a larger value might give better accuracy in some cases, but at a higher cost.
