Definition of MATRIX ALGEBRA. : generalized algebra that deals with the operations and relations among matrices.
Introduction [edit]. Many of the problems you will solve in linear algebra require that a matrix be converted into one of two forms, the Row Echelon Form (ref) and its stricter variant the Reduced Row Echelon Form (rref) . These two forms will help you see the structure of what a matrix represents. If the matrix represents a system of linear equations, these forms allow one to write the solutions to the system. Every Computer Algebra System and most scientific or graphing calculators have commands which produce these forms for any matrix.
