WebThe Haversine (or great circle) distance is the angular distance between two points on the surface of a sphere. The first coordinate of each point is assumed to be the latitude, the second is the longitude, given in radians. The dimension of the data must be 2. D ( x, y) = 2 arcsin [ sin 2 ( ( x 1 − y 1) / 2) + cos ( x 1) cos ( y 1) sin 2 ... WebY = 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.
