the Matrix (mathematical concept)

A matrix is a rectangular array of numbers arranged in rows and columns, similar to a grid or table. It serves as a compact way to represent and manipulate data or mathematical relationships, such as transformations, systems of equations, or networks. Matrices can be added, multiplied, and inverted, enabling complex calculations efficiently. They are fundamental in fields like engineering, computer graphics, and data science, helping to model real-world problems where multiple variables interact. Think of a matrix as a structured way to organize information that allows for powerful mathematical operations.
