scipy.spatial.distance.seuclidean

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

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:

seuclidean : double

The standardized Euclidean distance between vectors u and v.
