this development will help to develop your program nicely. please read it and make improvement.

说明：  用matlab实现SVM，并与BP神经网络进行对比(Implement SVM, with matlab and compare it with BP neural network)

说明：  凯泽窗低通，带通，高通数字滤波器，在matlab上的源程序！(matlab！)

在看了网上的四轴飞行器的源码后，修改的自己认为比较简单的四轴飞行器工作源码(After reading the online source quadrocopter, modify yourself think a relatively simple job quadrocopter source)

详尽的介绍了100个非常有实际意义的matlab程序，可以帮助初学matlab的人尽快的掌握一定的知识。(Detailed introduction to the 100 very meaningful matlab program that can help people as soon as possible matlab beginner to master certain knowledge.)

本程序需要用到MATLAB遗传算法工具箱，但是遗传算法工具箱有很多种，这里使用GEATbx工具箱，该工具箱是由英国Sheffield大学开发。(This program requires MATLAB genetic algorithm toolbox, but there are many genetic algorithm toolbox used here GEATbx toolkit, which was developed by the University of Sheffield, UK.)

能够计算进行有限元和扩展有限元的简单计算(FEA and XFEM matlab code can do a single crack in elastic analysis)

利用ESPRIT方法求目标的角度,系统为均匀线阵，阵元间距为波长的一半(Estimate the DOA of the target)

It should be noted that there is still room to improve the speed and the memory usage of the algorithms, using for instance displacement structure algorithms for the RQ decomposition and Lanczos algorithms for the SVD.

文件是 天线与电波传播 第3版 2017 的课件资源。 该书围绕天线与电波传播两大内容展开。全书共 14 章。前9章为天线部分，各章内容分别为：天线基础知识、简单线天线、行波天线、非频变天线、缝隙天线与微带天线、手机天线、测向天线、面天线、新型天线；后5章为电波传播部分，各章内容分别为：电波传播的基础知识、地面波传播、天波传播、视距传播、地面移动通信中接收场强的预测。(The document is the courseware resource of the third edition of antenna and radio wave propagation 2017. The book launches around two main contents: antenna and radio wave propagation. The book consists of 14 chapters. The first nine chapters are the antenna section, which includes the basic knowledge of antenna, simple wire antenna, traveling wave antenna, non-frequency-varying antenna, slot antenna and microstrip antenna, mobile phone antenna, direction finding antenna, surface antenna and new type antenna, and the last five chapters are the radio wave propagation section, which includes the basic knowledge of radio wave propagation, the ground. Wave propagation, sky wave propagation, line of sight propagation, and prediction of received field strength in ground mobile communication.)
