基于Matlab的优化算法，文件里面包含模拟退火法等多种遗传算法。(Optimization algorithm based on Matlab, the file which contains a wide range of genetic simulated annealing algorithm)

在MATLAB环境下对图像二值化处理后对图像进行edge的边缘提取，用于数值图像处理的相关领域中。(In the MATLAB environment on the image binarization edge of the image edge extraction, related fields for numerical image processing.)

关于Matlab2012经典超强教程，很实用，适合初学者(About Matlab2012 classic super tutorial, very practical, suitable for beginners)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)

上传一个一维粒子滤波的实例程序，很有用的，希望对大家有帮助(Upload a one-dimensional particle filter example program, very useful, we want to help)

这是第一版的AsymPDC工具包。用来处理PDC，gPDC和iPDC有关内容。运行环境为Matlab,并且要求至少Matlab中预装了3个工具箱：控制系统，信号处理和统计工具箱。(This is the first public release of AsympPDC package. It deals with the asymptotic statistics for PDC, gPDC and iPDC. AsympPDC runs under Matlab and is a practically self-contained except for requires routines from three Matlab toolboxes: Control System, Signal Processing, and Statistical. It is not extensively tested yet. It was partially tested under Windows, Macintosh and Linux environments with Matlab version 7.0 and higher. Please report any incompatibility to ksameshi[at]usp.br or baccala[at]lcs.poli.usp.br. Additionally for cosmetic purposes, the pdc_xplot routine uses several Matlab users contributed codes: subplot2.m (modified old version of supbplot to control spacing between subplots), shadedplot.m (developed by Dave Van Tol), suplabel.m (for label and title plotting in subplot figures, by Ben Barrowes), suptitle.m (contributed by Drea Thomas, for adding title above all subplots), and tilefigs.m (for tiling figures for simultaneous visualization, by Charles Plum))
