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 - 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.
