Matrices

A matrix is a rectangular arrangement of numbers, symbols, or expressions, organized in rows and columns. Think of it like a spreadsheet or a grid. Matrices are used in various fields, including mathematics, computer science, and physics, to represent and manipulate data. They can be used for solving systems of equations, transforming graphics, and even within algorithms for machine learning. Each element in a matrix can be accessed by its position, making it a powerful tool for handling large sets of information efficiently.
