在“浅析VC与Matlab联合编程（一）”中简单介绍了VC与matcom的接口编程，实现了VC调用matcom的一个基本功能，要真正熟练使用接口编程，还要对函数调用有一定了解。本文通过一个实例，较详细的介绍如何在VC中调用matcom编译后的函数。-The port program of VC and matcom is simplely introduced in the book-brief analysis of VC and Matlab combination program (part one), a basic function by using VC calling matcom can be achieved. But if you want to truly master the port program you must have some comprehension of the calling of function.That how to call the function after matcom compilation is related in detail by an example in this paper.
