double ReferenceValue (IVector parameters)
 Returns the value of this function at the specified parameter in the reference coordinate system.
void ReferenceGradientPlain (IVector parameters, IVector gradient)
 Calculates the first derivative (gradient) of this function at the specified parameter in the reference coordinate system.
void ReferenceHessianPlain (IVector parameters, IMatrix hessian)
 Calculates the second derivative (Hessian) of this function at the specified parameters in the reference coordinate system.

Properties
