以matlab实现数字水印的生成和提取，用的是高斯随机序列生成的易碎的隐式数字水印。(to Matlab digital watermark generation and extraction, using a Gaussian random sequence generation of friable implicit digital watermarking.)

This example is based on the integration of interactive simulation environment simulink to do, mainly based on simulink modeling equations, gives the spring mass damper system. We hope to learn about simulink help.

这是我在做浅海水声信道建模时收集的一些资料和程序，有一定的参考价值，分享给大家(This is some of the information and procedures I was doing shallow water channel modeling the collection, there is a certain reference value for everyone to share)
