History and Development of Matrices
Matrices were first used in ancient Chinese mathematics in 'The Nine Chapters on the Mathematical Art' to solve systems of linear equations. Modern matrix theory was established by Cayley and Sylvester in the 19th century, and with the development of computers in the 20th century, matrices became essential mathematical tools in all fields including science, engineering, and economics.
