说明：  通过将喷泉码的编译码方法再无线衰落信道上的用matlab仿真出来(Multi-path ruili channel simulation research on matlab)

Denoising technique using matlab

极坐标3d画图程序，功能很强大，自己看帮助吧(POLARPLOT3D Plot a 3D surface from polar coordinate data)

monto carlo optimization code

使用matlab编写的仿真带多普勒频移的单信道模型(Prepared using the matlab simulation with Doppler shift of the single-channel model)

说明：  拉伸具有调节的功能 大家试试看，我自己在书上总结的( The stretch has adjustment function everybody to try to look that I summarize in the book )

rough fuzzy c means algorithm for clustering of data set

IA_LD是用免疫优化算法（immune algorithm）解决物流配送中心选址（Logistics and Distribution）的问题。文件打开后运行IA_LD.m文件即可得到结果，代码中有详细注释，方便修改。运行示例已经保存为图片附在压缩包中。(IA_LD is immune optimization algorithm (immune algorithm) to solve the logistics distribution center location (Logistics and Distribution) problem. Run IA_LD.m file to get the file to open the result, the code has detailed notes, easy to modify. Run the sample has been saved as a picture attached to the compressed package.)

基于matlab对混沌现象进行研究，同时通过建立sum模型分析混沌吸引子的影响(study base on matlab)
