Constructor Details

Rand

public Rand(GeneralFunction function1, GeneralFunction function2)

Constructs a new Rand

Parameters:

function1 - the upper bound of the range

function2 - the lower bound of the range

Method Details

getInstance

public BinaryFunction getInstance(GeneralFunction function1, GeneralFunction function2)

Description copied from class: BinaryFunction

Returns an instance of this GeneralFunction, using the correct subclass

Specified by:

getInstance in class BinaryFunction

Parameters:

function1 - Constructor parameter 1

function2 - Constructor parameter 2

Returns:

an instance of this GeneralFunction

toString

public String toString()

Description copied from class: GeneralFunction

Returns a String representation of this GeneralFunction

Specified by:

toString in class GeneralFunction

Returns:

String representation of this function

clone

public GeneralFunction clone()

Description copied from class: GeneralFunction

Returns a clone of this GeneralFunction

Specified by:

clone in class GeneralFunction

Returns:

a clone of this function

getDerivative

public GeneralFunction getDerivative(String varID)

Description copied from interface: Differentiable

Returns the derivative of a GeneralFunction with respect to a variable. Should not be used in general; GeneralFunction.getSimplifiedDerivative(java.lang.String) is strongly preferred.

Parameters:

varID - the ID of the variable that is differentiated against

Returns:

the derivative of the function with respect to varID

evaluate

public double evaluate(Map<String,Double> variableValues)

Description copied from interface: Evaluable

Evaluates a GeneralFunction at a point denoted by a Map

Parameters:

variableValues - the values of the variables in the GeneralFunction at the point

Returns:

the value of the GeneralFunction at the point

simplify

public GeneralFunction simplify()

Description copied from interface: Simplifiable

Returns this GeneralFunction, simplified

Returns:

the simplified function
