# Matrix Multiplication — Normal Function to an Optimised Code If you are not familiar with matrix multiplication. In this article, we will learn different ways of multiplying matrices from an easy-to-read function to an optimized code.

In this article, we will learn different ways of multiplying matrices from an easy-to-read function to an optimized code.

﻿If you had read my previous articles on matrix operations, by now you would have already know what a matrix is. Yes, a matrix is a `2D` representation of an array with `M` rows and `N` columns. The shape of the matrix is generally referred to as dimension. Thus the shape of any typical matrix is represented or assumed to have (`M` x `N`) dimensions.

• Row Matrix — Collection of identical elements or objects stored in `1` row and `N` columns.
• Column Matrix — Collection of identical elements or objects stored in `N` rows and `1` column.

Note — Matrices of shapes (`1` x `N`) and (`N` x `1`) are generally called row vector and column vector respectively.
