Research on Non-linear Effects of Solitary Waves Based on Matlab

WANG Hong-mei,JI Guang-ming(College of Management Science,Chengdu University of Technology,Chengdu 610059,China)  
Solitary wave plays a major role in many natural sciences fields,which is one of important concepts of promoting the development of nonlinear science.It is also a unique phenomenon in development process of nonlinear equation.The existence of solitary wave is proved from the theoretical side of KdV equation.By using Matlab software to draw solitary wave map and to analyze its characters,the nonlinear of KdV equation is eliminated and its wave map is drawed to compare with solitary wave map,then a conclusion that the nonlinear of KdV equation play a major role for existence of the solitary wave map is summarized.
