As David said, that is just NumPy's `dot`. >>> a = np.array([0,2]) >>> b = np.array([5,0]) >>> theta = np.arccos(np.dot(a,b)/np.sqrt(np.dot(a,a)*np.dot(b,b))) >>> theta 1.5707963267948966 >>> theta/np.pi 0.5 hth, Alan Isaac _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
