E04HCF

 
Checks that a user-supplied routine for evaluating an objective function and its
first derivative values are consistent with the function values calculated.
 
Classes  :  G4c . Check user-supplied derivatives for optimization
            F3 .  Service routines for solution of nonlinear equations (e.g.,
                check user-supplied derivatives)
