此为雷达对抗的基本知识.对初始学习的人有一定的帮助.(This is the basic knowledge of radar confrontation. For the initial study were certainly helpful to them.)

说明：  1/3倍频程分析。有需要做这方面研究的同志们可以好好看一下。(1/3 octave analysis. There is a need to do research in this area can be a good look comrades.)

matlab for DWT 離散小波轉換(matlab for DWT Discrete Wavelet Transformation)

了一些资料，都没有说这个仿真平台是什么，是matlab还是直接在VC++的编译环境编程？还是有专门的仿真环境呢？ 3、如果用实物验证的话，我觉得有两种方式：一是用摄像头来采集整个地图信息，智能车的位置也有摄像头来反馈；二是，整个地图保存在内存中，小车根据传感器信息自我定位，然后和保存的地图比较。(You can download the current points to 1, the source download get points one day, you can download up to 20 times. [View your upload log] [continue to upload source to increase points] You have recently downloaded the 240 source code, you should contribute something new other friends 【Source】 it? Joined the group】 【QQ, blowing boasting a chat. You can also create a QQ group you join the union,)

说明：  2D的FDTD程序，有关边界的设定，物理参数的设定等，对学习FDTD很有帮助。(2D of the FDTD program, setting the boundaries, the physical parameters of the set and so helpful in learning FDTD.)

在VC中用Matlab引擎计算实对称矩阵特征值和特征向量。.mor0为矩阵输入文件，.mor位结果输出文件。(Calculated using Matlab engine in the VC real symmetric matrix eigenvalues ​ ​ and eigenvectors. . Mor0 matrix input files,. Mor-bit result output file.)

matlab编写的文本分类的程序，可以对已经分好词的文本进行分类，先自己导入数据，用libsvm中的svm进行分类和预测，特征用tfidf算法，还利用卡方检验进行了特征选择，可自行设定阈值。(matlab prepared text classification program, you can have a good word of text classification, classification and prediction using libsvm in svm, characterized by tfidf algorithm, also used the chi-square test was used for feature selection, you can set thresholds on their own.)

基于传递函数描述的3输入3输出DMC控制器设计代码，有详细的备注，可编译运行(DMC controller design method)

在带限信道信号传输的仿真。仿真4PAM调制信号在AWGN信道下的性能，画出误比特率和误符号率。 (In the band-limited signal transmission channel in the simulation. Simulation 4PAM modulated signal in AWGN channel performance.)

利用粒子群算法实现多边形的找圆心问题，对凸多边形适用。使用简便。(Particle swarm algorithm to find the center of the polygon problem, convex polygon apply. Easy to use.)
