在C语言中包含一个头文件UbigraphAPI.h，便可以像往常一样用循环语句“画”一个环，展示出图论模型的三维结构（需下载Ubigraph软件）-Contains a header file UbigraphAPI.h in the C language can be as usual loop " paint" a ring, demonstrating the three-dimensional structure of the graph theory model (s

该程序实现了VB与matlab的混合编程，编程方法是利用MATLAB建立COM组件，即形成DLL，然后在VB上进行调用。实现了在VB上进行复杂数学运算，并画出了三维图形。这是本人一个星期学到的东西。特此拿来与大家分享。(This program realizes the mixed programming of VB and matlab, the programming method is to use matlab to establish COM component, namely to
