The transformation given by the system of equationsĪn matrix consists of rows and columns, and the set of matrices with real coefficients is sometimes denoted In his 1867 treatise on determinants, C. L. Dodgson (Lewis Carroll) objected to the use of the term "matrix," stating, "I am aware that the word 'Matrix' is already in use to express the very meaning for which I use the word 'Block' but surely the former word means rather the mould, or form, into which algebraical quantities may be introduced, than an actual assemblage of such quantities." However, Dodgson's objections have passed unheeded and the term "matrix" has stuck. Matrix are identically zero." However, it remained up to Sylvester's collaboratorĬayley to use the terminology in its modern form in papers of 18 (Katz "Form the rectangular matrix consisting of rows andĭeterminants that can be formed by rejecting any one column at pleasure out of this Sylvester (1851) subsequently used the term matrix informally, stating In its conventional usage to mean "the place from which something else originates" The array itself (Kline 1990, p. 804), Sylvester used the term "matrix" Interested in the determinant formed from the rectangular array of number and not Lines and columns, the squares corresponding of This will not in itself represent a determinant,īut is, as it were, a Matrix out of which we may form various systems of determinants In his 1851 paper, Sylvester wrote, "For this purpose we must commence, not with a square, but with an oblong arrangement of terms consisting, suppose, of lines and columns. The matrix, and its close relative the determinant,Īre extremely important concepts in linear algebra,Īnd were first formulated by Sylvester (1851) and Cayley. In particular, everyīy a matrix, and every matrix corresponds to a unique linear A matrix is a concise and useful way of uniquely representing and working with linear transformations.
