这是我从网上找到的阴历算法，出于对原作者的尊重，代码里的各内容多于保留。-This is what I found in the lunar calendar online algorithm, based on the original author of respect, the code"s content than reservations.

程序可区分大小端模式，将.c中的#define LITTLE_ENDIAN去掉即是大端模式。.c中有具体调用实例和输出函数。 该算法效率极高，可用于商业用途，但请遵守GPL。

此程序是本人编写的在MFC环境下调用Matlab函数进行编程的实例-This procedure is, I prepared to call in the MFC environment Matlab function programming example
