摘要: The class of complex modified Korteweg-de Vries (CMKdV) equations has many applications. One form the CMKdV equation been used to create models for nonlinear evolution plasma waves , propagation transverse in a molecular chain, and generalized elastic solid. Another traveling-wave double homoclinic orbit. In this paper we introduce sequential parallel splitstep Fourier methods numerical simulations above equation. These are implemented on Origin 2000 multiprocessor computer. Our experiments have shown that finite difference inverse scattering give accurate results considerable speedup.
