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 <bool>  - 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.
