找到一个矩阵里的最小值,因而找到最小值很容易的(find a min number in a matrix,so you can get it essay)

matlab 日内趋势交易代码(TrendIntraDay trade codes of matlab)

本代码适用于随机场中的KL正交展开，可用于描述参数的空间变异。(This code is suitable for KL orthogonal expansion in random fields and can be used to describe the spatial variation of parameters.)

matalab程序好用便捷，关于宏观经济，有增长，有波动研究。(matalab program easy to use and convenient, on the macro economy, there is growth, there are fluctuations in research.)

feature selection algorithm

首先在m脚本文件canshuo.m中输入节点个数和路径权重，在命令窗口中输入canshu，用s=12,e=10的格式输入要求的起止点，再输入main即可得到两点之间的路径和长度。(M script file canshuo.m first enter the node number and the right path lies in the command window enter canshu, with s = 12, e = 10 The format of the input requirements of the start and end points, and then enter the main between two points can be obtained path and length.)

通过比较奇异谱图和高阶奇异谱图得出结论：高阶奇异谱分析能够更好的二次确定嵌入维数。最后根据Takens嵌入定理进行相空间的重构。(By comparing the spectra of singular spectrum and higher-order singular conclusion: High singular spectrum analysis to better determine the embedding dimension of the secondary. Finally, according to Takens embedding theorem for phase space reconstruction.)
