OFDM with qpsk in AWGN channel and the channel model

说明：  这是一个画等值线的图形源程序文件，比较实用(This is a contour drawing graphics source file, more practical)

基于boundar边界提取轮廓，采用曲率算法确定可能为指尖或者指根点的区域，采用该程序确定指尖指根区域。(Contour extraction based on boundar border, using the curvature method to determine the root may refer to point fingers or regions that use the procedure to determine the root area fingertips.)

program of matlab GUI 精通matlab GUI光盘代码(Proficient in matlab GUI CD code)

说明：  MATLAB的300个应用实例，对初学者极有帮助，有益于掌握MATLAB的各种工具。(MATLAB Application of 300, very helpful for beginners, good for a variety of tools to master MATLAB.)

粒子群算法（PSO）解决tsp问题-berlin52(Particle swarm optimization (PSO) for tsp-berlin52)

本目录主要包括：文档和两个源代码。 其中一个源代码是识别程序的，另一个是一个矩阵类库的，书里面也使用过，所以一并附上。 因为已经保存了训练好的网络权值，所以第一次使用识别程序时，可以直接运行\Release目录下的可执行文件，然后对图片目录中的测试图片进行读入、识别。 当然读者也可以自行用训练样本训练网络，不过要特别注意训练样本的选择，否则可能造成识别率很低。训练样本选择的原则是，尽可能的有代表性，在训练时间不至于太长的情况下，训练样本数目尽量多。 (This directory includes: documentation and two source code. One of the source code is to identify the procedure, the other is a matrix class library, the book which is also used, so be attached. Have been saved because of the trained network weights, so the first use of identification procedures, he can run Release directory Under the executable file, then the test image directory read pictures, identification. Of course, readers are free to use the training samples to train the network, but pay special attention to training samples, otherwise it may result in knowledge Do not rate very low. Training sample selection principle is that as far as possible, representative, in the long training time Buzhi Yu s case, the training Training sample size as much as possible.)

this code can be used to compute classic harmonic analysis

摄影测量学重要内容：单像空间后方交会（非常实用）(Photogrammetry: single space resection)

This program is an implementation of the k-means algorithm with matlab.
