这是MATLAB GUI制作鲁棒性数字水印的完整程序，很适合做毕业设计的同学参考(This is a MATLAB GUI robust watermark produced a complete program, it is suitable for those students graduate design)

没会用，大家看看吧。工具箱这个是，我没太弄明白，也不是很会用，会用的真心麻烦您给个回复(never use it)

说明：  基于信息熵的免疫算法，将信息熵算法与免疫算法相结合。(Immune algorithm based on information entropy)

利用函数MadHG生成规则LDPC码的校验矩阵H，其行重为6,列重为3,行数为列数一半(行数越大越好)，H中任意两列没有围长为4的圈，并得到H对应的生成矩阵G，可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),(use function MadHG Generation rules LDPC check matrix H, re-6, series of three, out for a few half of the number (A bigger the better), H 2 arbitrary no girth of the four circles, H counterparts and with the formation of matrix G, we can be assured of mod (G* H, 2) = 0. To be used : [H, G] = MadHG (m, n, x), x = 1 (the G part of the Left Front units) or 2 (G right half of the units RUF),)

matlab程序 主成分变换代码 以及测试数据(Principal component transformation matlab program code, and test data)

数字信号处理中采样定理和卷积定理的验证，简单易懂的matlab源码，(Validation sampling theorem and convolution theorem of the digital signal processing in the matlab source code, easy to understand)

自己编写的GABPM文件，用于基于数据的系统的辨识，辨识效果还不错。(This is a M file of GABPNN I have written for the identification based on data.The simulation result shows that the method is valid.)

齿轮箱故障诊断实用技术，可以有效掌握齿轮箱具体的故障诊断方法和步骤。(Practical gear box fault diagnosis technology, can effectively grasp the gearbox fault diagnosis methods and steps of the specific. )
