EPSEVSLSetDamping#

Set the type of damping to be used in EVSL.

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSEVSLSetDamping(EPS eps,EPSEVSLDamping damping)

Logically Collective

Input Parameters#

  • eps - the linear eigensolver context

  • damping - the type of damping, see EPSEVSLDamping for possible values

Options Database Key#

  • -eps_evsl_damping <damping> - set the type of damping

Notes#

Damping is applied when building the polynomial to be used when solving the eigenproblem, and also during estimation of the DOS with the KPM method.

See the documentation of EVSL [Li et al., 2019] for details.
