convolution, capture, envolvente EMG, pulse PWM and trasformation code in matlab compared matlab own

说明：  一个OFDM信号产生以及解调程序，用matlab编写(OFDMmatlab)

对lorenz信号的（svd）奇异值分解降噪，( lorenz signal noise singular value decomposition )

matlab 批量读DBF文件，非常好用，需要下载一个dbfread函数文件(matlab batch read DBF files, very easy to use, need to download a dbfread function file)

In this demo, I use the EM algorithm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: Nando de Freitas, Mahesan Niranjan and Andrew Gee Nonlinear State Space Estimation with Neural Networks and the EM algorithm After downloading the file, type "tar -xf EMdemo.tar" to uncompress it. This creates the directory EMdemo containing the required m files. Go to this directory, load matlab5 and type "EMtremor". The figures will then show you the simulation results, including ROC curves, likelihood plots, decision boundaries with error bars, etc. WARNING: Do make sure that you monitor the log-likelihood and check that it is increasing. Due to numerical errors, it might show glitches for some data sets.

We propose a novel fluorescence emission difference microscopy (FED) system based on focusing cy- lindrical vector beams. In conventional FED, a Gaussian beam and a 0–2 π vortex phase plate are used to generate solid and hollow spots. We focus radially polarized and azimuthally polarized cylindrical vector beams to obtain an expanded solid spot and a shrunken hollow spot, taking advantage of the optical properties of cylindrical vector beams to improve the conventional FED performance. Our novel method enhances FED performance
