formant feature voice its important for extraction 14 coofeecient from lp

小波包分解并能提取特征频段能量的完整的matlab程序(The wavelet packet decomposes and can extract the full matlab program of feature frequency energy)

说明：  利用matlab软件编写的格子玻尔兹曼方法模拟的圆柱绕流问题，并实现了可视化(The flow around the cylinder is simulated by lattice Boltzmann method compiled by MATLAB software, and the visualization is realized)

个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。是主函数的源程序，优化函数则以m文件的形式放在fitness.m里面，对不同的优化函数只要修改fitness.m就可以了通用性很强。(Procedures is the most basic particle swarm optimization procedures, using Matlab realize, is very simple. Is the main function of the source, optimizing the function with m the form of documents on fitness.m inside, optimized for different functions as long as the modifications can fitness.m highly generic.)

本程序是独立成分分析算法的主程序，在该程序中，通过调用子程序的方式实现了独立成分分析。但本程序不含子程序。(This procedure is the main independent component analysis algorithm, in this program by calling the subroutine way to achieve an independent component analysis.)

说明：  学习过程中，书写的完整代码，运行效果不错的哦(In the process of learning to write the complete code, the effect of a good run Oh)

北航张志勇编的matlab绘图程序，可作为初学者的参考(series of the Beijing University of Aeronautics and Astronautics Zhang Zhiyong Matlab mapping procedures, can be used as a reference beginners)

SVM的matlab接口．为利用SVM进行分类提供了一个matlab的环境(SVM Matlab interface. For the use of SVM classification of a Matlab environment)

说明：  simulink系统仿真：10kV 母线短路容量为10MVA，通过额定电压10/0.4kV，额定容量为100kVA，短路阻抗为5％的变压器与负荷相连， 阻感负荷RL 容量为50kVA，功率因数0.9。电力电子装置产生的5 次和7 次谐波电流均为5A；为了抑制7 次谐波在400V 母线处接入电容与变压器构成7 次滤波器。(simulink System Simulation: 10kV busbar short-circuit capacity of 10MVA, through the rated voltage 10/0.4kV, the rated capacity of 100kVA, short-circuit impedance of 5 of the transformer and load connected to sense the load resistance RL capacity 50kVA, power factor of 0.9. Generated by power electronic devices 5 and 7 harmonic currents are 5A to suppress harmonics in the 400V bus 7 access to capacitors and transformers constitute at 7 filter.)
