自己编写的可能性c均值聚类算法。数据需要自己load，里面有main函数,改成自己的数据就可以运行。比模糊c均值更加鲁棒的一种聚类算法，缺点是容易产生重合聚类。(possibilistic c means clustering algorithm.)

让某一频率以下的信号分量通过，而对该频率以上的信号分量大大抑制的电容、电感与电阻等器件的组合装置。 (low-pass filter )

randgen(mu,mu1,mu2,cov1,cov2,cov3) = Random generation of Gaussian Samples in d-dimensions where d = 2 mu, mu1, mu2 = (x,y) coordinates(means) that the gaussian samples are centered around cov1, cov2, cov3 are the covariance matrices and will vary changing the shape of the distribution, example: cov = sigma^2*Identity Matrix, where sigma^2 = a scalar N = the number of gaussian samples used are provided as user input, A test set of N/2 and a training set of N/2 gaussian samples is also generated Output is directed to the command window and a plot of the distributions are generated

The graphical methods of data analysis are as important as the descriptive statistics to collect information the data. In this section we will see some of these specialized plots available in the Statistics toolbox and also others MATLAB main toolbox

matlab的函数大全，按字母排序分类，是初学者的最佳选择。(matlab a function of Guinness, in alphabetical order classification, is the best choice for beginners.)

功能：用BFGS算法求解无约束问题：min f(x) 输入：x0是初始点，fun,gfun分别是目标函数及其梯度； varargin是输入可变参数变量，简单调用bfgs时可以忽略它， 但是其他程序循环调用时将会发挥重要作用 输出：x,val分别是近似最优点和最优值，k是迭代次数。(Function: BFGS algorithm for unconstrained problem: min f (x) Input: X0 is the initial point, fun, gfun each objective function and its gradient varargin variable parameter is the input variable, it can be ignored when a simple call bfgs , but other programs will play an important role when the cycle is called output: x, val are approximate optimum and the optimal value, k is the number of iterations.)

说明：  RBF神经网络，用于系统辨识 很好的文件(RBF neural networks for system identification)
