All Implemented Interfaces:

AbleRd, java.io.Serializable

public class AbleFuzzySetGaussian

extends AbleFuzzySet

implements java.io.Serializable

This class defines the Able data gaussian fuzzy set. A gaussian set is a bell-shaped curve useful for representing fuzzy numbers. The slope of membership goes to zero very quickly with a very short tail.

Constructor Detail

AbleFuzzySetGaussian

public AbleFuzzySetGaussian(AbleFuzzyVariable theParentVar,
                            java.lang.String theSetName,
                            double theAlphaCut,
                            double thePtCenter,
                            double theWidth)

Create a new fuzzy set.

Parameters:

theParentVar - A reference to the fuzzy variable that contains this fuzzy set.

theSetName - The name of this fuzzy set.

theAlphaCut - The low cut-off value for this fuzzy set.

thePtCenter - The point around which the curve is centered.

theWidth - A number that influences the width of the curve, whose overall shape is hard to predict. Typical values are from 0.9 through 5.0 inclusive, although any value greater than zero is allowed.
