【 摘 要 】

Linear problems with inexact initial data are examined. The stopping rules for certain iterative methods designed for solving linear equations and a linear elimination problem are proposed and analysed. In particular, these methods are applicable to ill-conditioned and ill-posed problems. Numerical results are presented that demonstrate the efficiency of these methods. (c) 2005 Elsevier B.V.
