% 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)
