implememtation of fisher algorithm using matlab

this matlab code is for drawing histograms of distributed/normal random samples,basic operations on signals as addition, multipication,delay.Drawing spectrum of signal.

说明：  通过RS分析计算hurst指数，可以直接计算整个时间序列，或者小波分解后各阶的H值。(Hurst index calculated by the RS analysis. It can calculate the H value of the time series directly , or after wavelet decomposition .)

AR模型的Yule-Walker方程.1927年，Yule提出用线性回归方程来模拟一个时间序列。Yule的工作实际上成了现代谱估计中最重要的方法——参数模型法谱估计的基础。Walker利用Yule的分析方法研究了衰减正弦时间序列，得出Yule-Walker方程，可以说，Yule和Walker都是开拓自回归模型的先锋。(The Higher-Order Yule-Walker method.)
