<Abstrcat>When using MATLAB/SIMULINK, a phase plain analyzing approach to analyze non-linear system is introduced. It can be used to automatically draw maps accurately, intuitively, easily,and fast. This approach can be used not only to conveniently and fast analyze the influence of parameters to characteristics,but also to conveniently model(needless to simplify), simulate,and automatically draw maps for multi-segments sophisticated structure system. It is a scientific, fast,and high efficient approach for analyzing and designing non-linear systems.
