差分法比较曲线的形状相似度，接着筛选出有用曲线求相位差，给了原始数据，可以直接运行-Difference Method for curve shape similarity, then filter out the demand curve useful in phase, to the raw data, can run

这个程序可以算某个特征时间序列的影响因素的相关性。具体是通过比较两个时间序列的曲线相似度实现的。运行该函数前要先输入特征时间序列和影响序列。-This program can be considered as a characteristic time series of the correlation between the factors. Specifically, by comparing the curve similarity of two time series. Before r
