说明：  众所周知，MATLAB是一个功能强大的数学软件，擅长于用矩阵运算完成各种数学功能。但是其程序需要在MATLAB环境下解释执行，效率不高。如果能将它强大的函数库用于C语言，利用C来编译执行，MATLAB将能发挥更大的作用。所以，MATLAB从5.0开始已经提供了与外部C/C++程序的应用程序接口，为利用C语言调用MATLAB的函数提供了可能。
(As we all know, MATLAB is a powerful mathematical software, specializes in the completion of matrix operations with mathematical functions. However, its procedures need to explain the implementation of MATLAB environment, efficiency is not high. If it can be a powerful function library for C language, using C to compile the implementation, MATLAB will be able to play a greater role. Therefore, MATLAB has been provided from the 5.0 to start with the outside C/C++ Process application programming interface for the use of C language function calls MATLAB possible.)
