scipy.spatial.distance.wminkowski(u, v, p, w)[source]

Computes the weighted Minkowski distance between two 1-D arrays.

The weighted Minkowski distance between u and v, defined as

\left(\sum{(w_i |u_i - v_i|^p)}\right)^{1/p}.

Parameters:

u : (N,) array_like

Input array.

v : (N,) array_like

Input array.

p : int

The order of the norm of the difference {||u-v||}_p.

w : (N,) array_like

The weight vector.

Returns:

wminkowski : double

The weighted Minkowski distance between vectors u and v.
