Detailed Description

Manhattan distance metric for vector types.

The ManhattanMetric, also known as the taxicab metric or the 1-norm, is a metric on the Euclidean n-Plane. The Manhattan distance between two points

\( P = (p_1, p_2, ..., p_n) \) and \( Q = (q_1, q_2, ..., q_n) \) is defined as \( \sum_{i=1}^{n} |p_i - q_i| \)
