Méthode Description
Clone ( ) : object

Creates a new object that is a copy of the current instance.

Derivative ( double x ) : double

Calculates function derivative.

The method calculates function derivative at point x.

Derivative2 ( double y ) : double

Calculates function derivative.

The method calculates the same derivative value as the Derivative method, but it takes not the input x value itself, but the function value, which was calculated previously with the help of Function method.

Some applications require as function value, as derivative value, so they can save the amount of calculations using this method to calculate derivative.

Function ( double x ) : double

Calculates function value.

The method calculates function value at point x.

SigmoidFunction ( ) : System

Initializes a new instance of the SigmoidFunction class.

SigmoidFunction ( double alpha ) : System

Initializes a new instance of the SigmoidFunction class.
