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 :

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.

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.
