语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

基于matlab的ICA语音信号的盲源分离代码，里面包含实际的混合语音，分析结果，结果还是挺不错的。(Based on Blind Source Separation of ICA matlab speech signal, which contains the actual mix of voice analysis results, the result was very good.)

读取地震数据的重要模块，这里包含了segy与su文件格式的文件读写还有一些基本的设置模块，非常强大和实用。具有独立性的模块，便于携带和复制！(Read seismic data module, file read and write segy su file format, there are some basic settings module is very powerful and practical. The independence of the modules, easy to carry and copy!)

This is a program to study the dynamic instability of cylindrical shell due to parametric excitation.

This project compares the performance of SOM versus LVQ in classification problems. Given two data sets: ‘iris.dat’ has 150 patterns of 3 classes with 4 features. ‘wine.dat’ has 178 patterns of 3 classes with 13 features. For SOM, use its algorithm (not use MATLAB tool), but for LVQ use MATLAB tool.
