摘　　要：A new multipoint scheme method is given for a kind of nonlinear evolution equation in this paper. Numerical experiments of KdV and MKdV equations are done by the new method. The results are compared with those of other numerical methods, and some graphical representations of the solitons are provided. It is proved numerically that the method is better than the other methods.A new multipoint scheme method is given for a kind of nonlinear evolution equation in this paper.
