Hu的7阶矩矩源代码，试过，可以用。挺不错的(Hu' s 7 moment the source code order moment, tried, you can use. Very good)

this file calculate reactive power of 39 buses ieee standard system with pso algorithm

成功实现计算LzehxN算法的程序，本人测试已经通过，性能已基本达到LzehxN算法的性能，需要MATLAB 2009b环境运行，如有问题，欢迎讨论 (The successful implementation of the program to calculate LzehxN algorithm, I have passed the test, need MATLAB2009b operating environment, any questions, please contact me )

五种常用滤波函数，巴特沃兹低通滤波、中值滤波等(5 different functions of filter)

复杂网络传染病传播模型在Matlab中仿真的资料，能够帮助研究网络中信息传播机制(Complex networks spread of infectious diseases in Matlab simulation model data that can help in information dissemination mechanism research networks)

用编写的集机器人设计、分析、仿真与一体的软件，非常有工程使用价值，完全可用！(prepared with the set robot design, analysis, simulation and integration software, it works very useful and it is perfectly possible!)

说明：  基于想要的主成分数量和精确度，采用matlab的pca函数进行主成分分析(Based on the desired principal component and accuracy, PCA function of MATLAB is used for principal component analysis)

matlab绘制CW信号的时域波形，同时对信号进行频谱分析，并考察采样频率以及信噪比对频谱分析的影响。(matlab draw CW signal time-domain waveform, and spectral analysis of signals and the sampling frequency and signal to noise ratio study of the impact of spectrum analysis.)

此段matlab代码实现数据的读入，可以自定义主成分的个数，也可以根据信息来那个的百分比来确定PC的个数(Paragraph matlab code data read into, you can customize the number of principal components, according to the percentage of the information that determines the number of the PC)

说明：  以一个五维系统为例，包含相图，时序图，lyapunov指数，分叉图，庞截面(Here are some very useful codes. I hope you can download them)
