An efficient method for computing the matrix product A multiplied by its transpose in Python (without using numpy)

If you have a list called A that contains only 0's and 1's in the form of nested lists, what is the most pythonic (and efficient) method to calculate the product of A * A' without relying on numpy or scipy? One way to achieve this using num ...

Attempting to perform matrix-vector and matrix-matrix multiplication utilizing loops in the Python programming language

Below is the code that I have written, but unfortunately, I keep encountering an error: import numpy as np matrix1 = np.array([(2, 3), (4, 5)]) vector = np.array([1, 2]) def matrix_vector_multiplication(matrix, vector): result = np.array([0 ...

Quick explanation of the concept of "matrix multiplication" using Python

I am looking to redefine matrix multiplication by having each constant represented as another array, which will be convolved together instead of simply multiplying. Check out the image I created to better illustrate my concept: https://i.stack.imgur.com/p ...
