非常好用，是一个在rayleighchan下OFDM检测的源代码，希望对大家有帮助(Very easy to use, is a next OFDM detection rayleighchan source code, in the hope that everyone has to help)

PERMANENT MAGNET SYM MAC MODELLING

该程序用于解决光学领域金属介质膜参数的问题，运行速度快。(The procedures for the settlement of the optical field of metal dielectric film parameter problem, fast running speed.)

说明：  】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。(The logistic- map sequences to encrypt the watermark are used. The original audio signal in DWT (Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is robust against some StirMark attacks.)

chi-square testing for lognormal distribution

说明：  混合Newton发求最小值.原理是基于Newton法，求解非线性方程。利用和最速下降法混合，避免了Newton的不足(ues mix Newton method to solve the problem: min f(x))

伪随机采样，97小波迭代收缩压缩传感，效果不错，方法简单(Pseudo-random sampling, iterative shrinkage of wavelet compression sensor 97, the effect is good, simple)

基于变分贝叶斯里理论的图像超分辨率重建技术，对于理解超分辨率技术有一定帮助。(In theory based on variational Bayesian image super-resolution reconstruction technique for understanding the super-resolution technology has certainly helped.)

MATLAB初级演示系统，用于绘制连续时间系统的零状态响应(MATLAB primary presentation systems used to map the continuous-time system, the zero-state response)

本源码是关于图像直方图的绘制原理，也就是matlab中imhist函数的实现方法。对初学图像的人有帮助。(imhist fuction )
