fast ICA的源文件 独立成分分析 MATLAB工具箱里也有 可以下载到工具箱 安装后就可以使用了(fast ICA Independent component analysis of the source file MATLAB toolbox is also available for download to install, ready to use the toolbox)

说明：  单位脉冲，单位阶跃，正弦函数等连续信号的MATLAB表达式。(pulse units, unit step, the sine function as a continuous signal MATLAB expression.)

针对激光光斑图像或荧光小球等图像进行高斯拟合定位其中心坐标。可同时定位一幅图像中的多个小球。要求对象模型符合高斯分布。(For laser speckle images or small fluorescent balls image gaussian fitting location and its center coordinates. Can be positioning an image of the multiple balls at the same time. Request object model conforms to the gaussian distribution.)

基于matlab的小波算法，给出了一个完整的算例，初学者可以很好的学习。(Based on the the matlab wavelet algorithm is given a complete example, beginners can learn well.)

程序来源：《复杂网络上的演化博弈》，这是一个规则网络上的牧鹿博弈(The source of the program is evolutionary game on complex networks, which is a deer game in scale-free networks.)

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 function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral / staggered A-B method, including attenuation modeled with two relaxation mechanisms. This example demonstrates harmonic generation within a plane wave given a B/A parameter of 5.2. To increase the distance of propagation, scale the sample grid (num_axpts) by a factor(s) of 2.( MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral /staggered A-B method, including attenuation modeled with two relaxation mechanisms.
