scipy.spatial.distance.sqeuclidean(u, v)[source]

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

The squared Euclidean distance between u and v is defined as

{||u-v||}_2^2.

Parameters :

u : (N,) array_like

Input array.

v : (N,) array_like

Input array.

Returns :

sqeuclidean : double

The squared Euclidean distance between vectors u and v.
