Answer:-
Matrix theory is a branch of mathematics that focuses on matrices, which are rectangular arrays of numbers, symbols, or expressions. It helps solve linear equations, perform transformations, and analyze systems in physics, engineering, and computer science. Matrices are widely used in machine learning, quantum mechanics, and economics to represent and manipulate data efficiently. The theory includes concepts like determinants, eigenvalues, and matrix inverses, which are crucial in solving complex problems. Simply put, matrix theory provides the foundation for handling multi-variable equations and is essential in various scientific and technological fields, making computations faster and more structured.
