WebGaussian elimination proceeds by performing elementary row operations to produce zeros below the diagonal of the coefficient matrix to reduce it to echelon form. 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.
