scipy.spatial.distance.seuclidean

scipy.spatial.distance.seuclidean(u, v, V)

Return the standardized Euclidean distance between two 1-D arrays.

The standardized Euclidean distance between u and v.

Parameters

u(N,) array_like

Input array.

v(N,) array_like

Input array.

V(N,) array_like

V is an 1-D array of component variances. It is usually computed among a larger collection vectors.

Returns

seuclideandouble

The standardized Euclidean distance between vectors u and v.
