Method Summary

double

distance(double[] vector1, double[] vector2) Calculates the distance between two vectors provided by argument vector1 and vector2.

Method Detail

distance

double distance(double[] vector1,
                double[] vector2)
                throws MetricException

Calculates the distance between two vectors provided by argument vector1 and vector2. A MetricException is thrown, if the dimensionalities of the two vectors differ.

Parameters:

vector1 - first vector.

vector2 - second vector.

Returns:

the distance between vector1 and vector2.

Throws:

MetricException - if the dimensionalities of the two vectors differ.
