All Implemented Interfaces:
DistanceFunction
public final class MinkowskiDistance extends Object implements DistanceFunction
Interesting distance function that will be a bit more expensive to compute (especially for large values of p) Also to note: p = 1 is the same as DistanceFunctionType.MANHATTAN and p = 2 is the same as DistanceFunctionType.EUCLIDEAN_SQUARED, so don't use this for p = 1 and p = 2!
