What Is a Matrix Data Structure?


Heather Bennett

A matrix data structure is a two-dimensional array that represents a collection of elements arranged in rows and columns. It is commonly used to store and manipulate data in various applications, such as mathematical operations, computer graphics, and scientific simulations. In this article, we will explore the concept of a matrix data structure and its significance in programming.

Defining a Matrix

Before diving into the details of a matrix data structure, let’s start by defining what a matrix actually is. A matrix is an ordered rectangular arrangement of numbers or symbols that can be represented as rows and columns. Each element in the matrix is uniquely identified by its row and column index.

Creating a Matrix

In HTML, we can create a matrix using nested <table> elements. The outer <table> represents the matrix itself, while each inner <tr> element represents a row, and each <td> element within the <tr> represents an individual element within that row.

Here’s an example of how to create a 3×3 matrix:


This will create a matrix that looks like this:

a b c
d e f
g h
