How to Create a Matrix of Matrices in Python?

Estimated read time 2 min read

To create a matrix of matrices in Python, you can use nested lists to represent the matrix and fill each element with a matrix. Here’s an example of how to create a matrix of matrices in Python:

# Define the dimensions of the matrix
rows = 3
columns = 3

# Create a matrix of matrices
matrix_of_matrices = [[[] for j in range(columns)] for i in range(rows)]

# Fill each element with a matrix
for i in range(rows):
    for j in range(columns):
        matrix_of_matrices[i][j] = [[i * j for k in range(3)] for l in range(3)]

# Display the matrix of matrices
for i in range(rows):
    for j in range(columns):
        print(matrix_of_matrices[i][j])

In this example, we first define the dimensions of the matrix: rows and columns. We then create a matrix of matrices using nested lists, where each element is initialized to an empty list using [].

We then use nested loops to fill each element of the matrix with a matrix. In this example, we fill each element with a 3×3 matrix where each element is the product of its row and column indices.

Finally, we use nested loops again to display the matrix of matrices. We print each element using the print function.

Note: You can modify this example to create a matrix of matrices with different dimensions or different types of matrices.
