scipy.spatial.distance.sqeuclidean(u, v, w=None)[source]

Computes the squared Euclidean distance between two 1-D arrays.

The squared Euclidean distance between u and v is defined as

\begin{align}\begin{aligned}{||u-v||}_2^2\\\left(\sum{(w_i |(u_i - v_i)|^2)}\right)\end{aligned}\end{align}
Parameters: u : (N,) array_like Input array. v : (N,) array_like Input array. w : (N,) array_like, optional The weights for each value in u and v. Default is None, which gives each value a weight of 1.0 sqeuclidean : double The squared Euclidean distance between vectors u and v.
