NEPSetProblemType#

Specifies the type of the nonlinear eigenvalue problem.

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPSetProblemType(NEP nep,NEPProblemType type)

Logically Collective

Input Parameters#

  • nep - the nonlinear eigensolver context

  • type - a known type of nonlinear eigenvalue problem

Options Database Keys#

  • -nep_general - general problem with no particular structure

  • -nep_rational - a rational eigenvalue problem defined in split form with all f_i rational

Notes#

Allowed values for the problem type are general (NEP_GENERAL), and rational (NEP_RATIONAL).

This function is used to provide a hint to the NEP solver to exploit certain properties of the nonlinear eigenproblem. This hint may be used or not, depending on the solver. By default, no particular structure is assumed.
