NEPRIISetHermitian#
Sets a flag to indicate if the Hermitian version of the scalar nonlinear equation must be used by the solver.
Synopsis#
#include "slepcnep.h"
PetscErrorCode NEPRIISetHermitian(NEP nep,PetscBool herm)
Logically Collective
Input Parameters#
nep - nonlinear eigenvalue solver
herm - a boolean value
Options Database Keys#
-nep_rii_hermitian
- set the boolean flag
Notes#
By default, the scalar nonlinear equation x’*inv(T(sigma))*T(z)*x=0 is solved at each step of the nonlinear iteration. When this flag is set the simpler form x’*T(z)*x=0 is used, which is supposed to be valid only for Hermitian problems.
