N2 - We propose several circulant preconditioners for systems defined by some functions g of Toeplitz matrices . In this paper we are interested in solving by the preconditioned conjugate method or the preconditioned minimal residual method, namely in the cases when are the functions , and . Numerical results are given to show the effectiveness of the proposed preconditioners.
