说明：  给出了通过MATLAB计算VaR的各种方法和实例(MATLAB code for Value-at-risk)

通过均值滤波、高斯滤波等实现图像平滑处理，使用MATLAB编程，完全无错能跑。(Image smoothing by mean filtering, Gaussian filtering achieved using MATLAB programming, completely error-free run.)

采用SVM高斯核，对样本进行分类，输入训练集和测试集，输出SVM分类准确率，采用10折交叉验证(This matlab code uses the SVM(support Vector Machine)to classify, and as the same time it uses the cross validation mathod.)

应用matlab求解线性随机微分方程dx(t)=sin(x(t))+sigma*dB(t)的输出结果。(generates outcomes of solutions of the SDE dx(t)=sin(x(t))+sigma*dB(t))

弗洛伊德算法，输入无向图中的任意两点的编号，可以得出两点间最短距离。解决最优化问题。(Floyd algorithm, the input undirected graph any two points in the number, the shortest distance between two points can be drawn. Solve the optimization problem.)
