EPSJDSetConstCorrectionTol#

Deactivate the dynamic stopping criterion (also called Newton).

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSJDSetConstCorrectionTol(EPS eps,PetscBool constant)

Logically Collective

Input Parameters#

  • eps - the linear eigensolver context

  • constant - if PETSC_FALSE, the KSP relative tolerance is set to \(2^{-i}\)

Options Database Key#

  • -eps_jd_const_correction_tol - set a constant or dynamic stopping criterion

Notes#

If this flag is set to PETSC_FALSE, then the KSP relative tolerance is dynamically set to \(2^{-i}\), where \(i\) is the number of EPS iterations since the last converged eigenvalue. By the default, a constant tolerance is used.
