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.
