将源码保存为.m文件，程序生成logR/S，在matlab中循环调用这个文件，生成多个不同时间尺度的logR/S，然后求出logR/S与logN的直线斜率即是Hurst。-Will be saved as a source. M documents, procedures to generate logR/S, in the cycle of calling matlab in this document, to generate a number of different time scales of logR/S, and then calculated logR/S and the linear slope of logn is Hurst.
