This file compares three different versions of the Kalman filter. The Kalman filter is used for recursive parameter estimation. The Kalman filter can handle noisy measurements. The first implemented filter (fcn_KF) is the Kalman filter with standard update of the covariance matrix P. The covariance matrix reflects the uncertainties of the predictions. To improve the numerical stability Potter developed a square root update (fcn_KF_SRP) of the covariance matrix P. Another version is the square root covariance update via triangularization (fcn_KF_SRT). This file generates a model. Then the three Kalman filters perform an estimation of the model parameter. At the end the results are compared. Sources: Simon, D. (2006): Optimal state estimation Kaminski, P. (1971): Discrete Square Root Filtering: A Survey of Current Techniques Golub, G.

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.
