How to get element-wise matrix multiplication (Hadamard product) in numpy?

Hello Guys, How are you all? Hope You all Are Fine. Today We Are Going To learn about How to get element-wise matrix multiplication (Hadamard product) in numpy in Python. So Here I am Explain to you all the possible Methods here.

How to get element-wise matrix multiplication (Hadamard product) in numpy?

1. How to get element-wise matrix multiplication (Hadamard product) in numpy?

However, you should really use array instead of matrixmatrix objects have all sorts of horrible incompatibilities with regular ndarrays.

2. get element-wise matrix multiplication (Hadamard product) in numpy

However, you should really use array instead of matrixmatrix objects have all sorts of horrible incompatibilities with regular ndarrays.

Method 1

For elementwise multiplication of matrix objects, you can use numpy.multiply:

import numpy as np
a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])
np.multiply(a,b)

Result

array([[ 5, 12],
[21, 32]])

However, you should really use array instead of matrixmatrix objects have all sorts of horrible incompatibilities with regular ndarrays. With ndarrays, you can just use * for elementwise multiplication:

a * b

If you’re on Python 3.5+, you don’t even lose the ability to perform matrix multiplication with an operator, because @ does matrix multiplication now:

a @ b  # matrix multiplication

Method 2

just do this:

import numpy as np

a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])

a * b
