EPSPowerSetUpdate#

Sets a flag to indicate that the residual is updated monolithically for nonlinear problems. This potentially has a better convergence.

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSPowerSetUpdate(EPS eps,PetscBool update)

Logically Collective

Input Parameters#

  • eps - the linear eigensolver context

  • update - whether the residual is updated monolithically or not

Options Database Key#

  • -eps_power_update - sets the update flag

Note#

This flag is relevant only in nonlinear problems, see EPSPowerSetNonlinear().
