Dijkstra最短路算法 flod算法：求任意两点之间的最短路.可以把矩阵直接带进去求解。(Dijkstra shortest path algorithm flod algorithm: seeking the shortest path between any two points. Can be brought directly into the matrix to solve.)

说明：  实现duffing方程的绘图，为工程上观察duffing混沌现象给出一个仿真的方法 (give a way to drew the picture of duffing)

在本讲义中，我们将着重讲述一些数学建模中常用的算法，包括神经网络算法、遗传算法、模拟退火算法和模糊数学方法。(In this lecture, we will focus on talk about some commonly used mathematical modeling algorithms, including neural networks, genetic algorithm, simulated annealing algorithm and fuzzy mathematics.)

基于matlab软件对雷达目标进行多普勒参数估计，用到Radon变换(Doppler parameter estimation of radar target based on MATLAB software, using Radon transform )

人工产生swissroll数据集，方便一些降维方法的效果验证(Swissroll generate artificial data sets to facilitate some of the effects of dimensionality reduction methods to verify)

图像纹理特征的提取程序，开发环境是matlab，可以对纹理的统计特征进行计算。(TextureAnlysis.m)

从任意一条单边路径开始。所有两点之间的距离是边的权，或者无穷大，如果两点之间没有边相连。 　　2，对于每一对顶点 u 和 v，看看是否存在一个顶点 w 使得从 u 到 w 再到 v 比己知的路径更短。如果是更新它。 　　3，不可思议的是，只要按排适当，就能得到结果。(A unilateral path from any start. All the distance between two points is the right side, or infinity, if there is no edge between two points connected. 2, for each pair of vertices u and v, to see if there is a vertex w from u to w and then to make than the known path v shorter. If you are updating it. 3, incredibly, just press the appropriate row, you can get results.)
