Numpy dot vs matmul in Python

  1. Numpy dot vs matmul in Python

    to Numpy dot vs matmul in Python use this method. By using this method you can Numpy dot vs matmul in Python. It is very easy to use. Lets learn about of this by given below example: import numpy as np arr1 = np.array([[3,2],[5,3]]) arr2 = np.array(([4,6],[4,7])) print(np.dot(arr1,arr2)) print(arr1@arr2) Output :
    [[20 32] [32 51]] [[20 32] [32 51]]

  2. Numpy dot vs matmul in Python

    to Numpy dot vs matmul in Python use this method. By using this method you can Numpy dot vs matmul in Python. It is very easy to use. Lets learn about of this by given below example: import numpy as np arr1 = np.array([[4,5,6], [3,2,1], [1, 2, 3]]) arr2 = np.array([[[6,7,8], [7,8,9], [1, 2, 3]]]) print("vector multiplication") print(np.dot(arr1, arr2)) Output : [[[65 80 95]] [[33 39 45]] [[23 29 35]]]

  3. np matmul

    To Numpy dot vs matmul in Python use this method. By using this method you can Numpy dot vs matmul in Python. It is very easy to use. Lets learn about of this by given below example: import numpy as np arr1 = np.array([[4,5,6], [3,2,1], [1, 2, 3]]) arr2 = np.array([[[6,7,8], [7,8,9], [1, 2, 3]]]) print("vector multiplication") print(np.dot(arr1, arr2)) Output : [[[65 80 95]] [[33 39 45]] [[23 29 35]]]

Method 1:

It is very easy to use. Lets learn about of this by given below example: 

import numpy as np
arr1 = np.array([[3,2],[5,3]])
arr2 = np.array(([4,6],[4,7]))
print(np.dot(arr1,arr2))
print(arr1@arr2)

Output :

[[20 32]
 [32 51]]
[[20 32]
 [32 51]]

Method 2:

It is very easy to use. Lets learn about of this by given below example: 

import numpy as np
arr1 = np.array([[4,5,6], [3,2,1], [1, 2, 3]])
arr2 = np.array([[[6,7,8], [7,8,9], [1, 2, 3]]])
print("vector multiplication")
print(np.dot(arr1, arr2))

Output :

[[[65 80 95]]

 [[33 39 45]]

 [[23 29 35]]]
