Introduction to Matrices

Explore the fundamentals of matrices, including how to traverse and transform 2D arrays. Understand key operations like addition, multiplication, transpose, and inversion, and see how these concepts apply to real-world problems such as image manipulation, computer graphics, and machine learning algorithms.

About the pattern

A matrix is a group of numbers arranged in rows and columns in a rectangular pattern. In computer science, matrixes are represented by 2D arrays with dimensions m×nm \times n, where mm is the number of rows, and nn is the number of columns. Each element in the matrix can be accessed using the array indexes. The first index represents the row, and the second index represents the column. For example, matrix[i][j]matrix[i][j] is an element from the ithi^{th} row and the jthj^{th} column of the matrix.

Matrix transformations are operations performed on matrices that result in a new matrix. There are several types of matrix transformations commonly used in mathematics ...
