چکیده
|
Three kinds of preconditioners are proposed to accelerate the generalized aor (gaor) method for the linear system from the generalized least squares problem. the convergence and comparison results are obtained. the comparison results show that the convergence rate of the preconditioned generalized aor (pgaor) methods is better than that of the original gaor methods. finally,some numerical results are reported to confirm the validity of the proposed methods. © 2013 xue-feng zhang et al.
