hurstcaculate
说明： hurst指数估计
This function does dispersional analysis on a data series, then does a
Matlab polyfit to a log-log plot to estimate the Hurst exponent of the
series.
This algorithm is far faster than a full-blown implementation of Hurst s
algorithm. I got the idea from a 2000 PhD dissertation by Hendrik J
Blok, and I make no guarantees whatsoever about the rigor of this approach
or the accuracy of results. Use it at your own risk.
