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
Returns: sqeuclidean : double
The squared Euclidean distance between vectors u and v.
