使用VisualStudio2008开发的VC调用matlab的示例小程序。matlab具有较强的数据运算能力，而VC可以提供一个较好的界面，因此把两者结合起来进行混合编程。本代码提供一个较好的显示。(VC call matlab using VisualStudio2008 developed sample applet. matlab has a strong computing power, the VC can provide a better interface, so to combine the two mixed programming. This code provides a better display.)
