阈值隐藏图像，图像通过阈值方式，把小图像隐藏到大图当中，实现信息隐藏，用于二值图像的信息隐藏(Threshold hidden image, the image by the threshold method, the small images to enlarge them hidden, to achieve information hiding for binary image information hiding)

说明：  在用matlab的时频分析中，不是所有信号的wvd都是可以，一些特殊的信号要用特殊的窗口来得到较好的效果(using Matlab in the time-frequency analysis, not all signals can be wvd, some special signal use special window to get good results)

一个简单的matlab的聚类算法程序，可以供初学者做参考资料。(A simple clustering algorithm matlab program can be used for reference for beginners to do.)

说明：  DMC,用matlab的M文件做的动态矩阵预测仿真的例子(DMC, with the M-file matlab to do the dynamic matrix of forecast simulation examples)

matal的卷积 z变化 和zturns 和izturns(matal convolution z changes and zturns and izturns)
