This code is used to cut selected part of the image that is of course after you decompress.   And run the code in the image circle separated.

利用MATLAB 画正太概率纸的方法，原程序，可以用于画出概率纸(By using the method of MATLAB to draw the teenage boy probability paper)

利用matlab模拟汽车泊车过程，用plot画出了整个过程(Use matlab simulate car parking process, with plot depicts the entire process)

无线通信领域的多径洒落源码程序，值得参考(The field of wireless communications multipath洒落source program, it is also useful)

使用matlab 实现ELM算法，可以用来分类的回归。

Hurst数计算，用于算法交易，非常有用(Hurst index)

简易四则运算计算器，使用时需将.m和.fig文件放到matlab工作目录下（本人使用的是R2013，放到bin文件夹即可，其他版本放到对应文件夹，有的是work文件夹），然后在命令窗口输入.m文件的文件名，即可显示一个简易计算器界面。有0-9九个数字供点击输入数，有重置和正负号按钮，界面简洁，功能耐用(Simple arithmetic calculator should be used with the. M and. Fig file into matlab working directory (I use the R2013, into the bin folder to the other versions into the corresponding folder, some work folder) , and then in the command window. filenames m file to display a simple calculator interface. 0-9 nine figures for the number of click enter, and the sign has reset button, the interface is simple, functional and durable)

通过仿真表明，该算法同几种经典的分布式算法相比，不但降低了发送功率，提高了用户效用，而且有较好的收敛性能，适用于对时延特性要求较高。(Through the simulation shows that this algorithm with several classic distributed algorithm, not only reduce the sending power, improve the user utility, and has better convergence performance, suitable for time delay characteristic request is higher. )

Code to simulate QAM modulation and demodulation. Also has an AWGN function to add noise to symbols. A Rayleigh and Rice process are added as a part to simulate a complete communication system and uate its behavior.
