31 Jan 2012 Spearman Rank Correlation It calculates the Spearman rank correlation coefficient. Author: Alexandros Leontitsis Daniel

If you want to compute tied ranks along a specific dimension of an ND-array see http://www.mathworks.com/matlabcentral/fileexchange/34560-tiedrankxdim.
29 Oct 2011 Rescaled Range Analysis Calculates the rescaled range analysis. Author: Alexandros Leontitsis Lars

I'm having some issues producing an output. Am I supposed to remove some ; or something? My intentions are to make a log(RS) log(n) plot. The program only yields a single number which doesn't make any sense.

Any help much appreciated.
