文件夹LSB中是空域LSB算法程序，文件夹COX中是Cox算法主要程序，文件夹DCT中是频域加在中频的算法的程序。 步骤：把LSB，COX，DCT三个文件夹考在MATLAB目录下； 运行lsb_embed,programme,dct2_embed_mod即可。其中PSNR.m是计算峰值信噪比程序；attact.m & robust.m是攻击程序。(Content: folder LSB of spatial LSB algorithm program, folder COX Cox algorithm is the main program folder DCT frequency domain is added to the IF algorithm program. Steps: the LSB COX DCT three files folder test in the MATLAB directory run lsb_embed program, dct2_embed_mod can. The which PSNR.m calculate the peak signal to noise ratio procedures attact.m & robust.m exploit.)

NOTE: This function modifies the BUTTONDOWNFCN of axes in the input list, and their children. However, it will not modify any object whose buttondownfcn is nonempty.

完成十余卷积过程，简单方便，能够这样那样这样，sorry(Convolution process more than a decade to complete, simple and convenient, this can be done this way, sorry)

说明：  几篇关于压缩感知方面的文章，都是大牛的作品，英文的，希望对研究这方面的同志有帮助(Several articles on compressed sensing aspects are the works of Daniel, the English, the comrades of research in this area)

关于卡尔曼滤波器进行时间序列的预测，有助于初学者的学习(Predictions about the Calman filter for time series, will help beginners to learn)

在CR网络中，能量检测是最基础，也是最重要的一个环节，该程序实现了能量检测算法。(Energy detection of CR network)

说明：  数值算法积分运算，可以将一组数据方程化后积分求解(quad in matlab)
