PEPLinearSetLinearization#

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

Synopsis#

#include "slepcpep.h" 
PetscErrorCode PEPLinearSetLinearization(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_linear_linearization <alpha,beta> - sets the coefficients

Notes#

See section Linearization for the general expressions of the linearizations. Note that the expressions are different depending on PEPProblemType.

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