Abstract:
      In this paper, we present some preconditioned generalized AOR (denoted by GAOR) methods for solving generalized least squares problems. We also compare the spectral radii of the iteration matrices of the our preconditioned and original methods. Finally, numerical experiments are provided to confirm the theoretical results.
