Definition of MATRIX ALGEBRA. : generalized algebra that deals with the operations and relations among matrices.
The term is also sometimes used informally to mean a vector, matrix, tensor, or other usually compound value that is actually reduced to a single component. Thus, for example, the product of a 1Ãn matrix and an nÃ1 matrix, which is formally a 1Ã1 matrix, is often said to be a scalar.
