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.

mpcc
MFCC,即倒谱系数,也是语音的一个特征之一,能够充分利用人耳的特性
% 具体的求法就是预处理,然后加窗,进行傅立叶变换,再求出功率普
% 然后得出其自然对数,最后进行dct变换
% 代码是用matlab写的,用到的一个语音工具箱,可以从网络上下载。(MFCC, that is, just a few pedigree, as well as a voice of one, to take full advantage of people's ears% of the specific characteristics of the solution is pretreatment, then increasing the window, Fourier transform, another sought power pu% then come to its natural logarithm, culminating transform% Extra code is written in Matlab. use of a voice box can be downloaded from the Internet.)
