MATLAB_filter

说明：  自己写的代码，实现了论文"Causal Modeling of Gene Regulatory Network"中的算法，运用了篇相关系数和遗传算法。(My own code, implementation of the paper "Causal Modeling of Gene Regulatory Network", using partial correlation coefficients and genetic algorithm.)

automatic threshold segmention

说明：  该程序是用matlab语言实现的关于瑞利信道多径传输的多谱勒效应的描述(that the procedure was used Matlab language on the Rayleigh Channel multipath transmission of the description of Doppler effect)

M=63 J=(M-1)/2 Wp=0.5*pi Ws=0.6*pi Np=100 Ns=100 weightp=1 weights=100 通带和阻带的加权系数 WpN=linspace(0,Wp,Np) WsN=linspace(Ws,pi-0.05,Ns) Wm=[WpN WsN] p=[ones(1,50),ones(1,50)/2] d=[p,zeros(1,Ns)] W=diag([weightp*ones(1,Np),weights*ones(1,Ns)]) C=cos(Wm*[0:J]) Q=diag(cos(Wm*0.5)) g=(W*Q*C)(W*d) g=g h=(g(J:-1:2)+g(J+1:-1:3))/4 h=[g(J+1)/4 h g(1)*0.5+g(2)/4] h=[h fliplr(h)] W=linspace(0,pi-0.1,512) H=freqz(h,1,W) plot(W/pi,20*log10(abs(H))) (filter design)

在未知方向发射信号，由接收阵元接收。对接收的信号使用MUSIC算法处理，得到发射信号方位(process the signals received using MUSIC to get the DOA)

matlab7简明教程，有电子教案，有源程序，非常适合自学，有心参加数学建模的下载，非常有用。(matlab7 simple tutorial, electronic lesson plans, source code, and is ideal for self-study, wants to join the Download of mathematical modeling, very useful.)

MATLAb code for lyot filter

说明：  一个相当不错的二维人物动画代码，大家可以学习学习。(a very good 2-D character animation code, we can learn from him.)

这是一个用于心电信号处理的工具包，研究心电方面的可用(this is used for ECG)

说明：  实现了基于mean-shift的图像检索，实现了比较两图像的相似度，选择最相近的图片(mean-shift)
