compute

public double compute(Vector a,
                      Vector b)
               throws CardinalityException

Compute the distance between two n-dimensional vectors.

The two vectors are required to have the same dimension.

Specified by:

compute in interface DistanceMeasure

Parameters:

a - The first vector.

b - The second vector.

Returns:

The distance between the two vectors.

Throws:

CardinalityException - if the array lengths differ.
