Matrices

Matrices are rectangular arrays of numbers, symbols, or expressions arranged in rows and columns. They are fundamental tools in mathematics, computer science, physics, and engineering, used to represent and solve systems of linear equations, perform transformations in graphics, model networks, and analyze data. Key operations include addition, multiplication, transposition, and inversion. Matrices enable efficient computation in fields like machine learning (e.g., neural networks), quantum mechanics, and economics. They come in various types—identity, diagonal, symmetric, sparse—each with unique properties.
