介绍了用matlab学习眼图的程序，效果还是很不错的。(Describes and learns the eye with matlab , the effect is very good)

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.)

通过对高通滤波器的理解，通过matlab编程，实现了窗函数法高通滤波器滤波(Through the high-pass filter to understand, through matlab programming, achieve a high-pass filter window function filtering)

此源码程序是自适应滤波中的NLMS算法的应用。在MATLAB中对其收敛速度 输出就行了仿真(This procedure is source of the NLMS adaptive filtering algorithm applications. In MATLAB in the convergence rate of its output on the line simulation)

蚁群算法是一种用来在图中寻找优化路径的机率型算法。是一种求解组合最优化问题的新型通用启发式方法，该方法具有正反馈、分布式计算和富于建设性的贪婪启发式搜索的特点。通过建立适当的数学模型，基于故障过电流的配电网故障定位变为一种非线性全局寻优问题。(Ant colony algorithm is a method used to find optimal path in the graph the probability-based algorithm. Is a combination of optimization problems to solve new general heuristic method, which has a positive feedback, distributed computing and constructive and the greedy heuristic search features. Through the establishment of an appropriate mathematical model, over-current fault-based distribution network fault location into a nonlinear global optimization problem.)
