Answer 2

Filling and Doubling a Matrix in Python

To fill a matrix of 8 rows and 5 columns with random numbers in the interval [-10, 10] and then double all its elements, you can use the NumPy library in Python.

First, let's fill the matrix with random numbers and display it:

import numpy as np

# Fill the matrix with random numbers
matrix = np.random.randint(-10, 11, size=(8, 5))

# Display the original matrix
print("Original Matrix:")
print(matrix)

The above code uses NumPy to create a matrix with random integers in the range [-10, 10] and then prints the original matrix.

Now, let's double all the elements of the matrix and display it:

# Double all elements of the matrix
doubled_matrix = matrix * 2

# Display the doubled matrix
print("\nDoubled Matrix:")
print(doubled_matrix)

The `* 2` operation doubles all the elements of the original matrix, and the resulting doubled matrix is then printed.

This code will fill the matrix with random numbers, display the original matrix, double all its elements, and then display the doubled matrix.

Note: The code snippets provided are based on the usage of the NumPy library in Python for matrix operations.
