说明：  matlab环境下bezier曲线,希望大家都多多共享出来,就好了(Matlab environment bezier curves, I hope you share a lot out!)

利用matlab实验人脸识别。从图像库中识别出相同人脸。主要运用LDA(Face recognition using matlab experiment. Identified from the image library same faces. The main use of LDA)

关于一个轴承故障分解程序，里面包含小波去噪，重构等，还有EMD模态分解，并且还有各种功率谱仿真图(About a bearing failure decomposition process, which contains the wavelet de-noising, reconstruction, etc., as well as mode decomposition EMD, and there are a variety of power spectrum simulation map)

this source code is very well

说明：  径向基函数神经网络（RBF）的MATLAB程序，比较详细，希望对学习RBF的人有帮助(Radial basis function neural network (RBF) of the MATLAB program, a more detailed study RBF people who want to help)

一种重要的辨识方法，主要用于对电力系统中低频振荡和其他运行方式的辨识(An important recognition method, mainly used for the identification of low-frequency oscillations in the power system and other running)

用汉宁窗函数法设计一个数字FIR高通滤波器，要求通带边界频率为500Hz，阻带边界频率为400Hz，通带最大衰减1dB，阻带最小衰减40dB，抽样频率为2000Hz，用MATLAB画出幅频特性，画出并分析滤波器传输函数的零极点(With han ning window function method to design a digital FIR high-pass filter, request bandpass boundary frequency for 500 Hz, stop-band boundary frequency for 400 Hz, bandpass biggest 1 dB attenuation, stop-band attenuation least 40 dB, sampling frequency for 2000 Hz, MATLAB draw the amplitude frequency characteristics, painted and analysis filter transmission function of zero poles)

基于人工神经网络的常用数字信号调制，包括脚本文件和函数文件形式，窗函数法设计一个数字带通FIR滤波器。( The commonly used digital signal modulation based on artificial neural network, Including script files and function files in the form, A window function design FIR digital band-pass filter.)

This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities using square array method. There are 2 programs, one for short and the other one is for acoustic long

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)
