战胜MATLAB必做50题，可以让你很快地活学活用MATLAB！！！(MATLAB will do over 50 questions, allowing you to quickly learn and use MATLAB! ! !)

说明：  灰色系统关于灰色绝对关联、灰色关联及灰色GM(1,1)的matlab代码(Matlab code gray Grey Absolute Correlation gray relational gray GM (1,1))

this is a M-file MATLAB that it can be solve a simple LP problem bye simplex method.

数据关联算法的matlab实现代码，主程序子程序都有，可以直接运行(Data association algorithm matlab code, main subroutine has, you can directly run)

一支持向量机有用的程序，希望对大家有用，我们一起学习进步。(A support vector machine useful procedure, useful for all of us hope that we learn and progress together.)

基于Harris原理的亚像素角点坐标检测Matlab程序；直接运行click_calib .m文件即可获得亚像素级角点坐标，附录Ⅱ中的其它函数文件均会被click_calib .m文件调用。(Based on the principle of subpixel Harris corner coordinates detection Matlab procedures run directly click_calib. M file to obtain sub-pixel corner coordinates, Appendix Ⅱ other functions in the file will be click_calib. M file called.)

bandwidth efficiency of shannon limit

matlab写的图像处理论文，用的是radon变换，对边缘很好(matlab image processing to write papers, using a radon transform, on the edge of good)

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected. This program gets around this by adding a fudge factor to the randn results to eliminate this problem. It took me ages to figure this out, I hope to reduce a similar effort for others

本文详细的介绍了FM信号产生和接收的方法，并给出了详细的matlab程序(producing and receiving FM signals)
