| 英文摘要 | We establish the omega-circulant preconditioned equations set P-N [omega] X-omega = B corresponding to the general Toeplitz equation set A(N)X = B. By choosing different criteria for constructing preconditioners, we obtain different preconditioned equation sets P-N[omega] X-omega = B and an optimal value for omega. Theoretical analysis and practical examples prove that the inversed results by the use of this method are much better than those of the traditional Fourier method. |
