distance

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

Description copied from interface: DistanceMetric

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

Specified by:

distance in interface DistanceMetric

Specified by:

distance in class AbstractMetric

Parameters:

vector1 - first vector.

vector2 - second vector.

Returns:

the distance between vector1 and vector2.

Throws:

MetricException - if the dimensionalities of the two vectors differ.
