every function has its own help which can be obtained by typing "help name" where "name" is the fu

function [mub,it] = calcMub(Xdat,seuil,itmax,epsilon);
%   function [mub,it] = calcMub(Xdat);
%
%   Compute upper bound value of fuzzy parameter
%
%   Xdat = data set of size (M,N)
%
%   Caution :
%   This funtion can take a lot of time when data set
%   has high dimensions. In such case we recommend to
%   compute the vector of distances using "C" or other
%   compiled langage and then use the function
%   "mub = searchMub(...)"

%   User can modify the following three parameters
%seuil = 0.03;   itmax = 500;    epsilon = 0.001;

cv_mub = seuil*M;
