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.
