Delivers the argument.

Constructor Summary

IdentFunction()

Method Summary

static <T> T	createFunction(String name, Class<T> as) Creates the transfer function, either with a one-dimensional argument as a Function or as a Multidimensional with an VectorG as argument.
static <T> T	createFunction(String name, String init, Class<T> as) Creates the transfer function, either with a one-dimensional argument as a Function or as a Multidimensional with an VectorG as argument.
double	derivative(double x) Calculates the first derivative of the function at the given argument value, i.e.
double	evaluate(double x) Given the value of the independant variable, this method returns the value of the function as a primitive double.

Method Detail

evaluate

public double evaluate(double x)

Description copied from interface: Function

Given the value of the independant variable, this method returns the value of the function as a primitive double.

Specified by:

evaluate in interface Function

derivative

public double derivative(double x)

Description copied from interface: Derivative

Calculates the first derivative of the function at the given argument value, i.e. we return df/dx(x).

Specified by:

createFunction

public static final <T> T createFunction(String name,
                                         Class<T> as)

Creates the transfer function, either with a one-dimensional argument as a Function or as a Multidimensional with an VectorG as argument. The target class must support the default constructor.

createFunction

public static final <T> T createFunction(String name,
                                         String init,
                                         Class<T> as)

Creates the transfer function, either with a one-dimensional argument as a Function or as a Multidimensional with an VectorG as argument. If the target class supports a default constructor, the init argument may be null, otherwise (the target class supports construction only with a single string argument), the initializer should be given.
