(1.7) and (1.8) lim E, 0, a sufficient condition that (1.9) lim (A+ E,)* At is that, for all sufficiently large n, the rows and columns of E, lie in the row and column spaces of A. He also gives a perturbation bound quite analogous to (1.5). The object of this paper isto show that under (1.7) and (1.8) a necessary and sufficient conditionfor (1.9) is that, for all sufficiently large n, rank (A+ E,) rank (A).
