How to generate random matrix in Numpy?

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

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)

As you can see, the rand function syntax requires you to provide just the number of rows and columns.

Using Random Randint method

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)

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