通过修改图像像素值的后4低位比特，实现随机0～1序列水印信息的嵌入(Modify the four low bit， accomplish embedding random 0～1 watermark sequence. )

关于matlab的基本绘图命令的有关教程，比较容易学，感觉不错，同大家分享(On matlab command the basic drawing the relevant tutorial, more easy to learn, feel good, with everybody share)

利用复自相关法求取混沌时间序列的时间延迟（tau），求取算法效率高且准确(Complex strike a chaotic time series autocorrelation time delay (tau), to strike a high efficiency of the algorithm and accurate)

此程序为信号阶次分析，主要针对汽车上振动噪声信号(Order this program for signal analysis, the main noise and vibration signals for the car)

此程序实现简单，便于阅读，易于理解，挺适合初学者学习的。(This procedure is simple and easy to read, easy to understand, very suitable for beginners to learn.)
