+function [D, M] = medAbsDev(X, DIM)
+% medAbsDev calculates the median absolute deviation 
+%
+% Usage:  D = medAbsDev(X, DIM)  
+%    or:  [D, M] = medAbsDev(X, DIM)
+% Input:  X  : data
+%         DIM: dimension along which mad should be calculated (1=columns, 2=rows) 
+%               (optional, default=first dimension with more than 1 element
+% Output: D  : median absolute deviations
+%         M  : medians (optional)
