摘要
围绕平面自治系统的相位图这个核心概念,利用MATLAB求解微分方程组的优势,得到了求解自治微分方程组相位图曲线、相位图方向场等各种算法的程序实现,实现了MATLAB仿真工具箱设计,利用图形用户界面(GUI)方法,设计了良好的人-机交互系统的主界面,最后给出了实际例子的程序运行结果,对推动微分方程组在具体实践中的应用和普及具有实际意义。
Around the plane autonomous system phase diagram is the core concept, using MATLAB to solve the differential equation group of advantage, obtained for autonomous differential equations of phase diagram, phase diagram orientation field and other algorithm program, realized MATLAB simulation toolbox for the design, using a graphical user interface （ GUI ） method, design a good man - machine interactive system main interface, finally gives the practical examples of the program running results, to promote the differential equations in the specific application and popularization, has practical significance.
