You can use the following methods to create a NumPy matrix with random numbers:

**Method 1: Create NumPy Matrix of Random Integers**

np.random.randint(low, high, (rows, columns))

**Method 2: Create NumPy Matrix of Random Floats**

np.random.rand(rows, columns)

The following examples show how to use each method in practice.

**Example 1: Create NumPy Matrix of Random Integers**

The following code shows how to create a NumPy matrix of random values that ranges from **0** to **20** with a shape of **7 rows** and **2 columns**:

import numpy as np #create NumPy matrix of random integers np.random.randint(0, 20, (7, 2)) array([[ 3, 7], [17, 10], [ 0, 10], [13, 16], [ 6, 14], [ 8, 7], [ 9, 15]])

Notice that each value in the matrix ranges between 0 and 20 and the final shape of the matrix is 7 rows and 2 columns.

**Example 2: ****Create NumPy Matrix of Random Floats**

The following code shows how to create a NumPy matrix with random float values between **0** and **1** and a shape of **7** columns and **2** rows:

import numpy as np #create NumPy matrix of random floats np.random.rand(7, 2) array([[0.64987774, 0.60099292], [0.13626106, 0.1859029 ], [0.77007972, 0.65179164], [0.33524707, 0.46201819], [0.1683 , 0.72960909], [0.76117417, 0.37212974], [0.18879731, 0.65723325]])

The result is a NumPy matrix that contains random float values between 0 and 1 with a shape of 7 rows and 2 columns.

Note that you can also use the NumPy **round()** function to round each float to a certain number of decimal places.

For example, the following code shows how to create a NumPy matrix of random floats each rounded to 2 decimal places:

import numpy as np #create NumPy matrix of random floats rounded to 2 decimal places np.round(np.random.rand(5, 2), 2) array([[0.37, 0.63], [0.51, 0.68], [0.23, 0.98], [0.62, 0.46], [0.02, 0.94]])

**Note**: You can find the complete documentation for the NumPy **rand()** function here.
