函数注册在Matlab和C++接口中起着重要的作用。在介绍函数注册作用的基础上，详细分析了函数注册的过程及应当注意的问题，并给出了一种实现函数注册的最简单的方法。用实例展示了函数注册的具体实现过程。

-registration function in Matlab and C interface plays an important role. In introducing the role of the registration function on the basis of a detailed analysis of the function of the registration process and should pay attention to the problem, and gives a registration function to achieve the most simple method. Examples demonstrate the function of the concrete realization of the registration process.
