public Func<Vector<double>, Vector<double>> GradientFunction { get; set; }Property Value
Func<Vector<Double>, Vector<Double>>A multivariate function returning a vector.
Remarks
If no gradient callback is supplied, numerical differences are used.
Supplied gradients must contain a finite value for every component;
otherwise a solve terminates with BadFunction.
Exceptions
| Invalid | The method is called while the algorithm is running. |
