Re: [Numpy-discussion] np.dot and 'out' bug

Hi Nicolas, Le 23/05/2013 15:45, Nicolas Rougier a écrit :

if I use either a or b as output, results are wrong (and nothing in the dot documentation prevents me from doing this):

a = np.array([[1, 2], [3, 4]]) b = np.array([[1, 2], [3, 4]]) np.dot(a,b,out=a)

-> array([[ 6, 20], [15, 46]])

Can anyone confirm this behavior ? (tested using numpy 1.7.1) I just reproduced the same weird results with numpy 1.6.2

best, Pierre
