Python Program to Multiply Two Matrices
In this example, we will learn to multiply matrices using two different ways: nested loop and, nested list comprehension.
In Python, we can implement a matrix as nested list (list inside a list).
We can treat each element as a row of the matrix.
For example X = [[1, 2], [4, 5], [3, 6]] would represent a 3x2 matrix.
The first row can be selected as X[0]. And, the element in first row, first column can be selected as X[0][0].
Multiplication of two matrices X and Y is defined only if the number of columns in X is equal to the number of rows Y.
If X is a n x m matrix and Y is a m x l matrix then, XY is defined and has the dimension n x l (but YX is not defined). Here are a couple of ways to implement matrix multiplication in Python.
