# NEPSetConstCorrectionTol

Sets a flag to keep the tolerance used in the linear solver constant.

### Synopsis

    #include "slepcnep.h"
    PetscErrorCode NEPSetConstCorrectionTol(NEP nep,PetscBool cct)

Logically Collective on NEP

### Input Parameters

| nep | - the NEP context
| cct | - a boolean value

### Options Database Keys

-nep_const_correction_tol <cct> - Notes: By default, an exponentially decreasing tolerance is set in the KSP used within the nonlinear iteration, so that each Newton iteration requests better accuracy than the previous one. The constant correction tolerance flag stops this behaviour.
