说明：  一个标准的粒子群优化算法程序，是用Matlab编程算例。(A standard PSO procedure is the use of Matlab programming examples.)

2 matlab files, combining to perform the Augmented Dickey-Fuller unit root test in Matlab. Useful for detecting auto-correlations and check for stationarity in time series, check for spurious regression, etc.

Numerical analysis: Newton method used to solve the nonlinear problems.

求解复杂网络的度及度分布、群集系数、平均路径长度等(Solving complex network of degree and degree distribution, clustering coefficient, average path length, etc.)

国外多变量反馈控制的最经典教材，全名为《多变量反馈控制_分析与设计》第二版，高清！(Multivariable Feedback Control- Analysis and Design_Second Edition)

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.

最小方差无畸变响应波束形成器，MVDR算法源码(The minimum variance distortionless response beamformer，MVDR algorithm source )

计算最小费用最大流的完整Matlab函数(Calculate the minimum cost maximum flow full Matlab functions)

经典的RLS算法，相信对做自适应滤波方向的人很有用哦(Classical RLS algorithm, adaptive filter do believe that one very useful direction Oh)

说明：  有用得MATLAB讲义，对MATLAB初学者非常有用(MATLAB helpful handouts on MATLAB is very useful for beginners)
