element wise multiplication python code example

Example 1: python element wise multiplication list

# element-wise multiplication of x & y
>>>x = [1,2,3,4]
>>>y = [2,3,4,5]
>>>[a*b for a,b in zip(x,y)]
[2, 6, 12, 20]

Example 2: np.multiply

>>> x1 = np.arange(9.0).reshape((3, 3))
>>> x2 = np.arange(3.0)
>>> np.multiply(x1, x2)
array([[  0.,   1.,   4.],
       [  0.,   4.,  10.],
       [  0.,   7.,  16.]])
