摘要
采用余弦微分求积法(CDQM)对(1+1)维非线性KdV-Burgers方程进行了数值求解.结果表明,所得数值解与方程的精确解相比具有明显的高精度且稳定性高,相对于其他常用方法,且公式简单,使用方便;计算量小,时间复杂性好.
The cosine expansion based differential quadrature method（CDQM） has been used to obtain numerical solutions to the （l＋l）-dimensional nonlinear KdV-Burgers equation. The numerical solutions are compared with the exact solutions, The results show that the nu- merical solutions are in good agreement with the exact solutions. Compared with someregulate methods; the computation efforts are relatively smaller and the time of computa- tion is shorter, it is also seen that the formulas of the method are very simple and easy to use.
