> Hi!
> There are five classes CanberraDistance, ChebyshevDistance,
> EarthMoversDistance, EuclideanDistance and ManhattanDistance in
> org.apache.commons.math4.ml.distance package, which compute different types
> of distances. Each of them contains method compute(double[] a, double[] b)
> that accepts two double arrays as variables.
> However, if the lengths of array a is greater than the length of array b, the
> method compute() in all the five classes produces
> java.lang.ArrayIndexOutOfBoundsException.
> For example,
> private void test0() {
> CanberraDistance distance = new CanberraDistance();
>
> final double[] a = { 1, 2, 3, 4, 9, 4 };
> final double[] b = { -5, -6, 7, 4, 3 };
> distance.compute(a, b);
> }
