minkowski-distance

http://en.wikipedia.org/wiki/Minkowski_distance
http://en.wikipedia.org/wiki/Lp_space

The Minkowski distance is a metric on Euclidean space which can be considered as a generalization of both the Euclidean distance and the Manhattan distance.

Minkowski distance is typically used with p being 1 or 2. The latter is the Euclidean distance, while the former is sometimes known as the Manhattan distance.

In the limiting case of p reaching infinity we obtain the Chebyshev distance.
