The term 'matrix' was probably first used in 1850 by J.J. Sylvester to describe "a rectangular array of numbers" from which determinants could be formed. Arthur Cayley, a contemporary of Sylvester, insisted that the idea of matrix preceded that of determinant and proceeded to define the operations of addition and multiplication of matrices themselves, as well as scalar 'multiplication', with great stress on square matrices. Probably his work laid the foundations for the conventional matrix theory of the present.
