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 form a DLL, then make the call on VB.The complex mathematical operation on VB is realized, and the 3d graphics are drawn.This is what I learned in a week.I hereby share with you.)
