+function R=tiedrank(X,DIM)
+% TIEDRANK compute rank of samples, the mean value is used in case of ties
+%  this function is just a wrapper for RANKS, and provided for compatibility 
+%  with the statistics toolbox of matlab(tm)
+% 
+%    R = tiedrank(X)
+%      computes the rank R of vector X
+%    
+% see also: RANKS
