This is matlab code for estimating the static linear system with Ridge Regression that is written by matlab 7.0. Here we want to estimate the below function: 1 - u^2 + 2*u^3 +u^5 +3*u^7 these are 2 files : without noise and with noise finally,there are plots for showing results.

信号包络求法,此法为hilbert变换和微分法的matlab源程序，有注释；(envelope curve calculation)

该程序是由matlab编写，可实现机器人的模糊自适应控制的仿真。(The program is written by matlab, enabling the simulation of fuzzy adaptive control of the robot.)

matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如修改不严重，可提取隐藏信息，如果修改过多，则只能确定是否有修改，而不知道隐藏的信息是什么(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, such as modification is not serious, can extract hidden information, if too many modifications, you can only determine whether changes were needed, they do not know what information is hidden)

rough set for clustering version 1

粗糙集约简的例子，求正域、生成未经处理的区分矩阵、对区分矩阵进行化简、求核、对已经处理过的区分矩阵进行属性约简(Rough intensive Jane, for example, generating positive field of untreated discernibility matrix, to distinguish matrix of reduction, for nuclear, to have treated discernibility matrix for attribute reduction )

Gauss Seidel Iteration

基于Matlab编程的QPSK的仿真，用处不错，简单明了(QPSK Matlab-based simulation programming, use good, simple)

this code is solution of optimal control
