摘要：

Consider the least squares solutions to Ax = b A ̄x = b ̄, where A ̄ = A + δA and b ̄ = b + δb are perturbed from A, b, respectively. In an earlier paper the author deduced the perturbation bounds for the solution when b ∃ R(A). In this paper we extend the results to cover more general cases when b ∉ R(A) and A is not of full rank. © 1990.
