Numpy's multiply(~) method performs element-wise multiplication given two arrays.

WARNING

Opt to use the * operator instead

If you don't need the 3rd and 4th parameters of this method, simply multiply two arrays using the * operator - you'll enjoy a performance boost.

Parameters

1. x1 | array_like

The first input array.

2. x2 | array_like

The second input array.

3. out | Numpy array | optional

Instead of creating a new array, you can place the computed mean into the array specified by out.

4. where | array of boolean | optional

Values that are flagged as False will be ignored, that is, their original value will be uninitialized. If you specified the out parameter, the behaviour is slightly different - the original value will be kept intact.

Return value

A scalar is returned if x1 and x2 are scalars, otherwise a Numpy array is returned.

Examples

Multiply by a common value

x = [2,6,9]
np.multiply(x, 2)
array([ 4, 12, 18])

Element-wise multiplication

x = [2,6,9]
np.multiply(x, [2,3,4])
array([ 4, 18, 36])
