WebDoing elementary row operations corresponds to multiplying on the left by an elementary matrix. For example, the row operation of "new R2 = R2 - 3R1" is produced on a 3 by n matrix when you multiply on the left by ( 1 0 0 − 3 1 0 0 0 1). Column operations, on the other hand, are produced when you multiply by a matrix on the right hand side.
