说明：  kmeans 算法的实现，编译已经通过，希望对大家有帮助(kmeans algorithm, the compiler has been passed and we hope to help)

this program used to acquire data through pc mic with 8khz sampling frequency. it collects data upto 2sec s duration, (can be varied) and reprodued

matlab中编写的一个计算PI参数的程序，可以自动整定控制系统的PID参数(PID controller caculate)

MATLAB在数字信号处理中的应用尤其是对于FIR一级IIR滤波器在MATLAB中的设计很有用途(MATLAB in Digital Signal Processing FIR one especially for IIR Filter Design in MATLAB in the very use)

matlab源程序 有点小错误但是稍微改下就可以了 人工免疫用于故障诊断源程序(matlab source code to change a little wrong, but under it a little artificial immune source for troubleshooting)

matlab实现ofdm的一些子程序模块，可以哦(ofdm matlab to achieve some of subroutine modules, can be oh)

This module will calculate the electrical angle between two different signals (Normally current + Voltage). once the first siganl as a reference signal and once the second signal as a reference signal.

Morlet小波带宽参数优化，利用shannon小波熵算法，非常实用。里面包括Morlet连续小波变化的实现(Morlet wavelet bandwidth parameters optimized using shannon wavelet entropy algorithm is very practical. Which includes the implementation Morlet continuous wavelet transform)

说明：  基于music算法的均匀圆阵方向估计，算法测试好用，可以下载(Uniform circular array direction estimation based on music algorithm. The algorithm is tested well and can be downloaded.)

是关于变结构控制的一个简单实例，其中包括控制函数的选取(on variable structure control a simple examples, including the selection control function)
