matlab一种基于混沌序列的魔方变换图像加密方案 重庆大学硕士论文(chaotic system，image encryption，magic-square algorithm， image-transmission)

本例用五点差分法求解一个二阶偏微分方程，其间用SSOR预处理的CG法处理，此实验可分别选取N=4，8，16，32(This example uses a five-point difference method for solving second order partial differential equations, during which the CG with SSOR pre-treatment, were selected for this experiment can be N = 4,8,16,32)

wavelet analysis，超级简单超级直观。一看就会了。(wavelet analysis, super simple and super-intuitive. Will be the one to see.)

激光散斑测量微流速，如果有散斑图，输入，给出相应的相对速度(find out the speed of laser speckle)

我们上课用的MATLAB课件，课件不错，就是老师讲的比较差劲。(the ppt of matlab used in my class)

聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)

MATLAB的梯度法源程序，按照提示输入，可直接运行(MATLAB source code of the gradient method, in accordance with the prompt input, can be directly run)

说明：  用MATLAB编写的svm源程序，可以实现支持向量机，用于特征分类或提取(MATLAB source code written using svm, support vector machine can be achieved for feature classification or extraction)
