distorion less data hiding using matlab simulation

说明：  2维的FDTD_MUR程序，可以用于点源程序的检验(Two-dimensional FDTD_MUR procedure can be used to test the source points)

一个简单的adaboost分类的方法。随机生成两组数据，训练分类器。之后再生成两组数据进行分类。效果很好(A simple way adaboost classification. Randomly generated two sets of data, to train a classifier. After re-generate two sets of data classification. Good results)

Plot coherent SNR improvement versus non-Coherent for different amounts of sample averaging

检测模块，可以检测电流、电压值等一些电学参数(check module ，check current,voltage,and etc)

对声音信号采样分析频谱,改变采样率，播放，音频信号加噪声(Spectrum analyzer of sound files)

matlab实现傅里叶变换和傅立叶反变换(Implement fft and ifft)

说明：  ER 模型网络生成的matlab代码 计算网络的度分布、集簇系数 网络科学作业 (ER model generate a random network of nodenum nodes with probability of 0.1 and calculate average degree, average clustering coefficient and degree distribution)

说明：  条件语句是编程中最常用的结构，这里作一个演示结果的文件(conditional statement is the most commonly used programming structure here for a demonstration of the results of the document)

实现数字图像盲水印的嵌入,利用变换域的方法。(realize the input of the blind watermark.)
