PEPSTOARSetLinearization#

Set the coefficients that define the linearization of a quadratic eigenproblem.

Synopsis#

#include "slepcpep.h" 
PetscErrorCode PEPSTOARSetLinearization(PEP pep,PetscReal alpha,PetscReal beta)

Logically Collective

Input Parameters#

  • pep - the polynomial eigensolver context

  • alpha - first parameter of the linearization

  • beta - second parameter of the linearization

Options Database Key#

  • -pep_stoar_linearization <alpha,beta> - Sets the coefficients

Notes#

Cannot pass zero for both alpha and beta. The default values are alpha=1 and beta=0.
