Method Detail

getFunctionHelp

protected java.lang.String getFunctionHelp()

Description copied from class: Function

Returns a help string describing the function and the parameters taken by the function

Specified by:

getFunctionHelp in class Function

initialize

public void initialize()
                throws java.lang.Exception

Description copied from class: Function

Calls initialize in the super class ParemeterizedObject which checks parameters

Overrides:

initialize in class Function

doGenerate

public void doGenerate()

Generates the table.

Specified by:

doGenerate in class ParameterizedObject

eval

public double eval(double x)

Evaluates the table, by finding nearest point.

Specified by:

eval in class Function

Parameters:

x - the point at which to evaluate the function
