This Matlab Code models a Rayleigh fading channel using a modified Jakes channel model. A modified Jakes model chooses slightly different spacings for the scatterers and scales their waveforms using Walsh–Hadamard sequences to ensure zero cross-correlation. alpha_n = frac{pi(n-0.5)}{2M} and eta_n = frac{pi n}{M}, results in the following model, usually termed the Dent model or the modified Jakes model: R(t,k) = sqrt{frac{2}{M}} sum_{n=1}^{M} A_k(n)left( cos{eta_n} + jsin{eta_n} ight)cos{left(2pi f_d t cos{alpha_n} + heta_{n} ight)}. The weighting functions A_k(n) are the kth Walsh–Hadamard sequence in n. Since these have zero cross-correlation by design, this model results in uncorrelated waveforms. The phases ,! heta_{n} are initialized randomly and have no effect on the correlation properties. Matlab fast Walsh-Hadamard transform function is used to efficiently generate samples using this model.

我在毕业设计时做的一个MATLAB实现图像的SIFT特征提取程序，并做在不同光照、不同视角下的 vZnbfT 特征匹配，还做了 zSCjeKh 特征值的提取转换，编译通过(I graduated the design of a MATLAB to achieve the image of the SIFT feature extraction process, and do in different light, different angles of the vZnbfT feature matching, but also to do the zSCjeKhfeature extraction and conversion, the compiler through)

matlab 的s函数模板，用s函数是，在这个基础上修改后就可以用了！！(matlab s-function template, use the s function is, on this basis can be modified after it! !)

利用matlab绘制图像灰度直方图，能够表现像素统计的结果(Using matlab to draw the image histogram, the statistical results can show pixels)
