说明：  MATLAB光学设计程序 MATLAB光学设计程序(Optical design program MATLAB)

emd 代码程序 音频信号的采集和分解，用来做经验模态分解实验。(emd-code program audio signal acquisition and decomposition, used as empirical mode decomposition experiment.)

The code can be used for calculating the element stiffness matrix of a q-4

说明：  matlab代码，轴承特征提取，包括rms、最大幅值、峰值因子、绝对平均值、平均值、峭度、脉冲因子、裕度因子、能量，小波包、经典模态分解等特征(Matlab code, bearing feature extraction, including rms, maximum amplitude, crest factor, absolute mean, mean, kurtosis, pulse factor, margin factor, energy, etc)

维纳噪声抑制；实验分析；实验结果及分析；利用信号之间的相关性进行信号估计，从而将噪声滤除(Wiener noise suppression Experimental analysis The experimental results and analysis Using the signal signal to estimate the association between, to filter out noise )

这个程序是杨儒贵研究生教材《高等电磁场理论》中的程序，讲解电磁场后向散射(This procedure is expensive Yang Ru graduate textbook "Advanced Electromagnetic Field Theory" program, to explain electromagnetic backscatter)

matlab是大家非常熟悉软件，本电子文档中提供了很多关于matlab的经典算法实现，希望能够帮助大家！(matlab is very familiar with U.S. software, the electronic documents to provide a lot about classical algorithm matlab realize, I hope everyone can help!)

基于Matlab音乐的分类算法以及相应的代码，最后给出了DSP的实现系统框图(Matlab-based music classification algorithm and the corresponding code, and finally given the realization of DSP system block diagram)

说明：  《matab小波分析》第五章的源代码，比较全！(&quot Matab wavelet analysis,&quot Chapter V of the source code, compare the whole!)
