sin 函数功能，用matlab，比较常用，大家可以做个参考(function of sin by matlab)

姿态估计的源码，可以快速算出xyz坐标，数据可以通过matlab等进行二次开发。(Pose estimation of source code, you can quickly calculate the xyz coordinates, matlab and other data can be secondary development.)

汉明码编码译码源码，谢谢大家分享，~~~~(Hamming code encoding decoding source code, thank you for sharing)

（9）鼠标器程序 主程序是shubiao.C，可以使用Turbo C工具来调试。((9) Program mouse The main program is shubiao.C, you can use Turbo C tools to debug.)

卫星导航的单点定位程序，设计简单，原理清楚，是学习编程的好资料。(Single point positioning satellite navigation application, simple design, the principle is clear, is good reference to learn programming.)

对于在Visual C++中调用Matlab应用程序接口，关键在于设置编译环境和使用正确的调用规则，然后，在发布软件时携带必要的动态连接库就可以保证程序的独立性(Matlab Application Program Interface in Visual C++ call, the key is to set the compiler environment and use the correct call rules, then carry the necessary dynamic link library publishing software program can guarantee the independence of)

这个程序使用vc++实现的一个工程，这个工程的作用就是完整实现了MATLAB和vc++混合编程的关键函数的功能-mexfunction。有其详细的开源代码！(This program uses the vc++ implementation of a project, the role of this project is to complete implementation of the MATLAB and vc++ mixed programming function of the key functions-mexfunction. Has its open source code in detail!)

说明：  基于非负矩阵分解（NMF）的人脸特征提取算法，NMF基本思想是找到一个线性子空间W，使的构成子空间的基本图像的像素点都是正值，而且人脸图像在子空间上的投影系数也是正数(Non-negative Matrix Factorization (NMF) of facial feature extraction algorithm, NMF basic idea is to find a linear sub-space W, so that the composition of sub-space of the basic image pixels are positive, and face image in the sub-space projection coefficient is positive)
