中文说明： 基于欧几里得距离的聚类分析，时间序列数据分析中的梅林变换工具，有较好的参考价值，添加噪声处理，可直接计算得到多重分形谱,利用最小二乘法进行拟合多元非线性方程。
English Description：
Clustering analysis based on Euclidean distance and Merlin transform tool in time series data analysis have good reference value. Adding noise processing, multifractal spectrum can be calculated directly, and the least square method is used to fit multivariate nonlinear equation.
