All Implemented Interfaces:

AbleRd, java.io.Serializable

public class AbleFuzzySetSegments

extends AbleFuzzySet

implements java.io.Serializable

This class defines the Able data segments fuzzy set. A segments set is a surface specified by point/truth-value pairs, with the line segments interpolated between the points. At least two pairs must be given, and any values falling outside the range of points have a 0.0 truth value.

                            double[] theTruthVector)

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.

theNumberOfValues - The number of elements in the following two arrays. The number must not be larger than AbleFuzzySet.MaxValues.

theScalarVector - An array of points within the domain.

theTruthVector - For each point in the above array, that point's truth value, a number from 0.0 through 1.0.
