How to generate random matrix in Numpy?

Let’s see how to generate random matrix using the NumPy library in Python.

numpy random array

Using Random Rand method

To generate Numpy matrix populated with random numbers use random Numpy module.

import numpy as np

random_array = np.random.rand(3, 3)

print(random_array)

However, there is also the possibility to generate an array in a different way. You can populate your array with integers within a specified range using the randint function.

import numpy as np

random_array = np.random.randint(0, 7, size=10)

print(random_array)

numpy random array range

Based on this code you probably know. 0 is low value and 7 is max one. Size of array is 10.
