Webthe elementary row operations that appear in Gaussian elimination are all lower triangular. On the other hand, since one can undo any elementary row operation by an elementary row operation of the same type, these matrices are invertibility and their inverses are of the same type. Since Lis a product of such matrices, (4.6) implies that Lis WebInteractively perform a sequence of elementary row operations on the given mx nmatrix A.
