Hi,
>From the dot documentation, I tried something simple:
a = np.array([[1, 2], [3, 4]])
b = np.array([[1, 2], [3, 4]])
np.dot(a, b)
-> array([[ 7, 10],
[15, 22]])
And I got expected result but 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]])
a = np.array([[1, 2], [3, 4]])
b = np.array([[1, 2], [3, 4]])
np.dot(a,b,out=b)
-> array([[ 6, 10],
[30, 46]])
Can anyone confirm this behavior ? (tested using numpy 1.7.1)
Nicolas
