It s matlab programs for Hamming codes. They re Hamming 4/7 and Hamming 11/14. Including encoder, decoder. I hope you enjoy them!

基于S函数BP神经网络的PID控制器的研究与学习，方便简单，实用性特别强。(S function based on BP neural network PID controller research and study, convenient and simple, practical particularly strong.)

说明：  基于matlab的图像处理及瑕疵自动检测(Matlab-based image processing and automatic detection of defects)

改进的稀疏度自适应正则化压缩采样匹配追踪算法，在自适应的基础上运用了正则化的思想(Improved adaptive sparsity regularization compressive sampling Matching Pursuit algorithm, based on the use of adaptive regularization ideas)

说明：  这个是RS的原代码，几个文件一起仿真，很有用的(This is the original RS code, with the simulation of several files, very useful)
