Abstract
In this work, we give an effective preconditioned numerical method to solve the discretized linear system, which is obtained from the space fractional complex Ginzburg–Landau equations. The coefficient matrix of the linear system is the sum of a symmetric tridiagonal matrix and a complex Toeplitz matrix. The preconditioned iteration method has computational superiority since we can use the fast Fourier transform and the circulant preconditioner to solve the discretized linear system. Numerical examples are tested to illustrate the advantage of the proposed preconditioned numerical method.
