这个仿真程序用于实现DS-CDMA通信系统仿真(The simulation program used to implement DS-CDMA Communication System Simulation)

用dwt函数实现了一层小波变换，并将各分量用图像显示了出来(Dwt function implementation with a layer of wavelet transform, and image display using the component out)

用Matlab语言实现Jacobi迭代算法、Gauss-Seidel迭代算法和逐次超松弛迭代法，求解一般的线性代数方程组问题(Jacobi Gauss-Seidel sor)

使用matlab，带GUI实现对图像的线性点运算(Use matlab, with a GUI implementation of linear dot image)

This is a matlab svm, very useful to the matlab virtual machine

2015年数学建模B题第一题答案，本程序已经在大赛之后提交，可以使用(2015 Mathematical Modeling B and that the answers to the first question, this program has been submitted after the contest, you can use)

提出了一种鲁棒的多水印嵌入与检测算法,该算法基于小波域,且提取水印时不需要原始图像,保护了原始图像的安 全。在该多水印算法中,提出并使用了一种将密码学和常规的数字水印制作方法- - - 叠加法和量化调制法,有机结合起 来的新的方法,在水印嵌入时,不同的水印,生成与该水印相关的不同的密钥,在进行水印的提取时,用不同的密钥和待测的 图像提取出相应的水印。通过将密钥向第三方注册,可以获得对原始图像的所有权。(A robust multi-watermark embedding and detection algorithm, the algorithm based on wavelet domain, and extract the watermark without the original image, protect the safety of the original image. In the multi-watermarking algorithm, will be presented and used a conventional cryptography and digital watermarking production method--- superposition method and quantify the modulation method, combine the new method, the watermark embedding different watermark, associated with the watermark generating different keys, making extraction of the watermark when tested with a different image key and the corresponding extracted watermark. By the key to a third party registration, can be obtained ownership of the original image.)

这是一个关于基于互信息的图像配准程序，是以matlab编写(This is a mutual information based image registration procedures, the preparation is matlab)
