Method Detail

getDistance

public double getDistance(double[] point1,
                          double[] point2)

Description copied from interface: DistanceFunction

This method returns the distance between point1 and point2. The dimenson of the points is represented by the length of the arrays. This method should return the same value as the method below, if points are equivalent!
