The
Manhattan distance, also known as the
L1-distance is the
distance between two points measured along axes at
right angles. In a
plane with p
1 at (x
1, y
1) and p
2 at (x
2, y
2), the Manhattan distance is:
- <math> (|x_1 - x_2|^m + |y_1 - y_2|^m)^\frac{1}{m}</math>, when m = 1.
It is so named because it is the distance a car would drive in a city laid out in square blocks, like Manhattan (neglecting that in Manhattan there are one-way streets and some oblique streets).
L2-distance is called Euclidean distance.
