matrix

A matrix is a rectangular array of numbers arranged in rows and columns, similar to a spreadsheet or grid. It’s a way to organize data or represent mathematical relationships, such as transformations or systems of equations. Each number in a matrix is called an element. Matrices are used in various fields—from computer graphics and engineering to statistics—to perform calculations efficiently. They allow compact representation of complex data and enable operations like addition, multiplication, and finding solutions to equations, making them a fundamental tool for managing and analyzing structured information.
