WebbY = cdist (XA, XB, 'mahalanobis', VI=None) Computes the Mahalanobis distance between the points. The Mahalanobis distance between two points u and v is ( u − v) ( 1 / V) ( u − v) T where ( 1 / V) (the VI variable) is the inverse covariance. If VI is not None, VI will be used as the inverse covariance matrix.
