说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

《模式分类》(原书第2版)电子档，，是模式识别和场景分析领域奠基性的经曲名著。( The pattern classification (the original book version 2) electronic archives, and is founding in the field of pattern recognition and scene analysis by the classics.)

fdtd计算无限长圆柱导体散射问题，可以计算RCS，包含解析解，此代码经过我自己的修改，与网络版本不同，更加好用(fdtd calculate infinite cylindrical conductor scattering problem, you can calculate RCS, it contains analytical solution, this code through my own changes, and network versions, easier to use)

本书系统介绍MATLAB遗传算法和直接搜索工具箱的功能特点、编程原理及使用方法。(This book systematically introduce MATLAB Genetic Algorithm and Direct Search Toolbox features, programming principles and use.)

MATLAB编写的3个简易计算器程序，hh那个是本人综合另两个写出来的，简易好用。具体用法不用我说了，大家将所有代码放在MATLAB安装文件的work里面即可。可能还需要GUI绘图，具体我忘了，一年前做的。(MATLAB prepared by the three simple calculator program, which is my hh another two comprehensive written, Simple handy. I do not have specific directions said, we will put all of the code of MATLAB installation work will be inside. May also need GUI drawings, specific, I forgot, a year ago to do.)
