Chebyshev谱法求解正则长波方程
The Solution of the Regularized Long Wave Equations Using the Chebyshev Spectral Method
摘要
Abstract
The regularized long wave equation is one of the most important nonlinear partial differential equations.In this paper,the Chebyshev spectral method is proposed to solve the regularized long wave equation,the Chebyshev polynomial and Chebyshev-Gauss-Lobatto are used to construct the derivative matrix,and the one-dimensional and two-dimensional regularized long wave equations are approximated as ordinary differential equations to prove the error estimation of the discrete Chebyshev spectral method and the solution is performed using a higher-order ODE solver.The numerical results obtained by the method are compared with the exact solution,and the effectiveness of the method is verified.The data results in this paper are more accurate than that of other methods.关键词
