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 momemts used in the method. The default value is 1, an larger value might give better accuracy in some cases, but at a higher cost.
