Web17 jul. 2014 · 42 If you would take the sum of the last array it would be correct. But it's also unnecessarily complex (because the off-diagonal elements are also calculated with np.dot) Faster is: ssq = np.sum (res**2) If you want the ssd for each experiment, you can do: ssq = np.sum (res**2, axis=1) Share Improve this answer Follow WebNumPy is the fundamental library for array containers in the Python Scientific Computing stack.
