NEPNLEIGSSetTrueResidual
Specifies if the solver must compute the true residual explicitly or not.
Synopsis
#include "slepcnep.h"
PetscErrorCode NEPNLEIGSSetTrueResidual(NEP nep,PetscBool trueres)
Logically Collective on NEP
Input Parameters
| nep | - the nonlinear eigensolver context
|
| trueres | - whether true residuals are required or not
|
Options Database Key
| -nep_nleigs_true_residual <boolean> | - Sets/resets the boolean flag 'trueres'
|
Notes
If the user sets trueres=PETSC_TRUE then the solver explicitly computes
the true residual norm for each eigenpair approximation, and uses it for
convergence testing. The default is to use the cheaper approximation
available from the (rational) Krylov iteration.
