KNN是一种有效的模式识别分类算法，本文件在Matlab平台实现KNN算法在模式识别中的运用。(KNN is an effective pattern recognition classification algorithms, this document is in the Matlab platform implementation KNN algorithm in the application of pattern recognition.)

说明：  本程序适用于解决优化问题，达到某些问题的优化目标。(This procedure applies to solve the optimization problem, the optimization problem to achieve certain goals.)

利用MATLAB实现屏蔽电缆转移阻抗解析法S.Sali模型，已调通。希望对大家有帮助，也可以用来学习MATLAB编程。(Use of MATLAB shield cable transfer impedance analytic method S.S ali model, has the expert. We want to help, but also can be used to study the MATLAB programming.)

it involves bask,bpsk,decomposition andlbp code,qpsk, and bpsk demodulation

optimization methods and algortihms

本程序实现一个MATLAB辅助工具，你可以借助它，选择plot绘制出的各个图像数据，并且随意拖动它们。另外，它还有两个不同形状任意大小的绘图刷子。你使用这个工具选中点的时候，这些点被高亮，直到释放鼠标。另外你还可以在命令行下面调用这个工具，选择绘制的图像(This program implements a MATLAB aids, you can make use of it, select the plot to draw out each image data, and easily drag them. In addition, it has two different shapes of any size drawing brush. You use this tool to select points, these points are highlighted, until you release the mouse. Also you can call the following at the command line tool, select the image to draw)

说明：  用MATLAB编写的BP算法在函数逼近中的应用。(BP algorithm using MATLAB written application in function approximation.)

dear sir i have uploaded a few programs for your consideration
