Hurst Exponent and Linear Fit

Code to find the Hurst exponent and shows the corresponding fit and statistics

Used to find the hurst exponent in matlab. Code takes in data and returns the rescaled range and length of intervals so you can use these if required. It performs the fit for the hurst exponent, provides coefficients and gives a graph to show this fit. If you can't use 'fitlm' package, then remove the end part of the code as instructed .
