Matrices Unit
A Matrix is a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix. Matrices have wide applications in engineering, physics, economics, and statistics as well as in various branches of mathematics.
The term matrix was introduced by the 19thcentury English mathematician James Sylvester, but it was his friend, British mathematician Arthur Cayley, who developed the algebraic aspect of matrices in two papers in the 1850's.
