Constructor Details

IntegerUnitaryFunction

public IntegerUnitaryFunction(GeneralFunction operand)

Constructs a new IntegerUnitaryFunction

Parameters:

operand - The GeneralFunction which will be operated on

Method Details

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

operate

public abstract long operate(int input)

Performs the operation of this function

Parameters:

input - the value to be operated on

Returns:

the result of the operation
