5.6.1.8. scipy.spatial.distance.braycurtis¶

scipy.spatial.distance.braycurtis(u, v)[source]¶

Computes the Bray-Curtis distance between two 1-D arrays.

Bray-Curtis distance is defined as

$$\sum{|u_i-v_i|} / \sum{|u_i+v_i|}$$

The Bray-Curtis distance is in the range [0, 1] if all coordinates are positive, and is undefined if the inputs are of length zero.

Parameters:	u : (N,) array_like Input array. v : (N,) array_like Input array.
Returns:	braycurtis : double The Bray-Curtis distance between 1-D arrays u and v.
