Communition MATLAB (Proakis)书中的源程序，很不错(Communition MATLAB (Proakis) source book, very good)

matlab的画图的程序使用，数形结合的重要工具，灵活掌握对于matlab开始的学习很重要。(matlab program to use the Paint, The Combination of the important tools, flexibility of learning for matlab start is important.)

对于matlab编程的一些风格的指南，感觉还是比较重要，特别对于初学者，分享一下啦(For some matlab programming style guide, I feel it is quite important, especially for beginners, to share it)

提出了一种可抗 几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向 量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法(We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual feature vector and encryption technology combine in the watermark without the original image is a practical blind watermarking algorithm)

matlab实现模糊C均值算法对样本进行分类。附件中国有样本库。( matlab in fuzzy c means in sorting)

在建模中方程求根时用到的matlab程序，可以更加迅速(Roots of equations in modeling when used matlab procedures can be more quickly)

说明：  脑电信号模式识别(EEG pattern recognition)

产生了一个正弦波，方波，三角波的db—sc调整信号的频谱，实现过程等(Produced a sine wave, square wave, triangle wave db-sc adjustment signal spectrum, the realization process, etc.)

说明：  STBC的源代码，用MATLAB实现，有说明，TXT文档，复制运行就行(STBC s source code, using MATLAB to achieve, it has made it clear, TXT files, copy to run on the line)
