用matlab实现的Gauss-Seidel迭代法。(Using matlab realize the Gauss-Seidel iteration method.)

在matlab环境下利用LSB最低有效位算法将一个图片水印隐藏在载体图片中，并对被隐藏那个信息进行提取。(Matlab environment in the use of least significant bit LSB algorithm will be a picture watermark hidden in the picture carrier, and that information has been extracted hidden.)

编写查找程序search，功能如下：给定任意有序数列，然后输入任意一数，用折半查找法找出该数在数列中的位置，若数列中有此数，则返回该数在数列中所在的位置，若数列中无此数，则返回-1 把给定值y插入到有序数组a（由大到小）中，插入后，数组中的数仍然有序 用递推法求解：一串字符以问号“？”结尾，顺序读入后反向输出，且统计其中字符的个数(prepare you search procedures, functions as follows : Given a series of arbitrary order, then enter an arbitrary number, using binary search method to find the few series in the position, if the series is this, Return of the few series in the location, if the series has been no such number,-1 is returned will be distributed to value y orderly array inserted into a (decreasing), insert after The array is an orderly with a few recursive method : a bunch of characters with a question mark "?" The end of the order after reading the reverse output and statistics on the number of characters)

基于pca算法的人脸识别软件，有界面，有注释，有图像库(Pca-based face recognition algorithm software, interface, with annotations, a image library)

南大赵其昌老师的文章，对于分析薄板振动的初学者有很好的指导作用(Nanda ZHAO Qi-chang teacher' s article, for the analysis of the vibration plate has a very good guide for beginners)

说明：  此PDF为一关于OFDM的文章，相当不错，而且带有实现的matlab程序。(here for a PDF of the article OFDM, which is pretty good, but with the realization of Matlab procedures.)
