国外著名控制专著《extremum seeking control and application》输出跟踪控制案例源码，采用matlab编写，对研究极值搜索控制理论非常有帮助(a well-known book about system control 《extremum seeking control and application》output tracking control matlab code, it will benefit to study the extremum seeking control theory for people)

设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。 对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。 (Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file. The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)

Gold序列因为其良好的伪噪声特性，经常作为CDMA扩频系统仿真中的用户扩频序列，用MATLAB可以产生各种长度的Gold序列优选对，在此基础上，产生混沌序列等其他性质的扩频序列也很容易。(MATLAB script for Illustrative Gold sequence generation)
