How to do matrix multiplication in NumPy

You can do matrix multiplication in NumPy with the following code. If you want to learn Python, I highly recommend reading This Book.

Example 1

import numpy as np
a = np.array([[2,4],[6,8]])
b = np.array([[1,2],[3,4]])
c = np.dot(a,b) 
print(c)

Output

[[14 20]
 [30 44]]

import numpy as np
a = np.array([[1,2,3],[4,5,6]])
b = np.array([[5,10],[2,4],[1,2]])
c = np.dot(a,b) 
print(c)

Output

[[12 24]
 [36 72]]
