scipy.spatial.distance.mahalanobis¶

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

Computes the Mahalanobis distance between two n-vectors u and v, which is defined as

where V is the covariance matrix. Note that the argument VI is the inverse of V.

Parameters : u : ndarray An -dimensional vector. v : ndarray An -dimensional vector. VI : ndarray The inverse of the covariance matrix. d : double The Mahalanobis distance between vectors u and v.
