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.
