Public Methods

Method	Description
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.
GaussianFunction ( ) : System	Creates a new GaussianFunction.
GaussianFunction ( double alpha ) : System	Creates a new GaussianFunction.
GaussianFunction ( double alpha, DoubleRange range ) : System	Initializes a new instance of the GaussianFunction class.
Generate ( double x ) : double	Samples a value from the function given a input value.
Generate2 ( double y ) : double	Samples a value from the function given a function output value.
