The term “matrix” refers to a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. A simple example is a table showing the scores of different players in a series of games. Each row might represent a player, and each column might represent a game, with the intersection of a row and column showing the player’s score in that specific game.
Matrices are fundamental in various fields, including mathematics, physics, computer science, and engineering. They provide a concise way to represent and manipulate data, enabling complex calculations and analyses. Historically, the concept of matrices emerged from the study of systems of linear equations and determinants. Their use has expanded significantly, playing a crucial role in areas such as computer graphics, machine learning, and quantum mechanics.
