L-M神经网络在matlab开发环境中的实现实例，有利于初学者学习与掌握(L-M neural network in the matlab environment development to achieve the example, be helpful for beginners to learn and master)

find Optimal point of camel function with simulated annealing.

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.)

将有的数据间隔大于10s的PKI数据与均匀10s的PRD数据整合成一个间隔<=10s的数据文件(Some data interval greater than 10s of the the PKI data with uniform 10s of the PRD data integration into an interval < = 10s data file)

THIS CODE IS USED TO ESTIMATE EMWA VAR WITH BACKTEST

This function removes random, high frequency noise originating from the electrodes. a) First, we use a simple low-pass filter. b) Second, we apply Donoho s method by writing the code. c) Third, we simply apply Matlab s thr function. It should be noted that the considered mother wavelet is Symmlet8.
