应用OFDM可以有效地对抗多径时延扩展。循环前缀不仅可以消除符号间干扰（ISI），还能消除子载波间干扰（ICI).本项目完整地仿真了OFDM系统。(Application of OFDM can effectively combat multipath delay spread. Cyclic prefix can not only eliminate inter-symbol interference (ISI), can eliminate Inter-carrier interference (ICI). This project a complete simulation of the OFDM system.)

This book is about how to make MATLAB-based Graphical User Interface (GUI) tools. It falls naturally into two parts: • GUI design, or how to make something that’s useful • GUI implementation, or how to make something that works The principles of good GUI design are, for the most part, timeless and universal. They apply in MATLAB as much as they apply anywhere else,though we consider them here with respect to specific examples. The guidelines for GUI implementation, on the other hand, tend to be much more specific—many of the implementation details we discuss here weren’t possible in MATLAB until recently. Accordingly, in this manualthere is a trend from the general to the specific. Part of the second half of the manual is devoted to the use of MATLAB’s GUI-building tool, Guide (Graphical User Interface Development Environment). A quick start example of how to use Guide also closes out this introductory chapter.

rar文件解压源码,为rarlab公司发布(source code for unrar-5.2.6,uppack the .rar files,for multi-os )

利用MATLAB编写的简单的NSGA2程序 ,实用方便 (Prepared using a simple MATLAB program NSGA2, practical convenience)

本程序基于“图像模式识别—VC++技术实现”写就，实现了线性和非线性手写数字识别。 程序主文件是homework.m 具体实现可以参考程序内注释。 (this is a matalb programme,in order to recognise the number writtern by yourself. it include homework.m,homework.fig,Getfeature.m,losstab.m,losstab.fig,samplelib.m,samplelib.fig,save_sample.m,save_sample.fig)

算法由于提供了一个预测值,相对来说有简化.第五种方法,也就是ode45所得的精度最高尺度到了1e-18...简直可怕!一般很少有工程问题是它不能够满足的了,能够看出,解的差别在本问题里已经很明显了. (algorithm providing a predictive value, a relatively simplified. Fifth, ode45 is the highest accuracy of a scale of e-18 ... is simply terrible! it seldom works that asked that is not able to meet it in the can see that the solution of differences in the issues it is already very clear.)
