LeastSquare

说明：  一个简单的MATLAB界面程序，可以让程序在界面操作上更友好(A simple MATLAB interface program that can make the program more friendly operation in the interface)

先随机找寻一个合理的初始划分，然后试探将样本从一个群搬到另一个群，如果某次搬动能使准则函数值得到改进的话，则继续搬运，否则废除本次搬运，再继续其他搬运。(Randomly and find a reasonable initial division, and then test the sample from a group of moving to another group, if a move can make the criterion function is worth to improve, it continues to handling, otherwise the abolition of the handling, continue to other handling.)

Mapping consist of QAM and QPSK modulation

trasform program good

qpsk干扰仿真，很不错的源代码，欢迎大家下载，(qpsk interference simulation, a very good source, all are welcome to download, Oh)

说明：  小世界网络生成,生成20个节点的小世界网络(small world network)

Exponentially weighted covariance matrix

模拟粒子散射，可以自己设定参数，模拟散射后的轨迹等等(Simulate particle scattering parameters can be set to simulate the scattering of the trajectories after)

说明：  男声，女声，乐器声音频谱分析和傅里叶转换(Male, female, musical instruments, sound spectrum analysis and Fourier transform)

数字PID的matlab仿真程序，针对刘金琨的先进PID控制的matlab仿真，里面的部分程序进行了修改(Digital PID of matlab simulation program for Liu Jinkun matlab advanced PID control simulation, which part of the program were modified)
