function [modes its]=ceemdan(x,Nstd,NR,MaxIter)

% WARNING: for this code works it is necessary to include in the same
%directoy the file emd.m developed by Rilling and Flandrin.
%This file is available at %http://perso.ens-lyon.fr/patrick.flandrin/emd.html
%We use the default stopping criterion.
%We use the last modification: 3.2007
% 
% This version was run on Matlab 7.10.0 (R2010a)
%----------------------------------------------------------------------
%   INPUTs
%   x: signal to decompose
%   Nstd: noise standard deviation
%   NR: number of realizations
%   MaxIter: maximum number of sifting iterations allowed.
%
%  OUTPUTs
%  modes: contain the obtained modes in a matrix with the rows being the modes        
%   its: contain the sifting iterations needed for each mode for each realization (one row for each realization)
% -------------------------------------------------------------------------
%  Syntax
%
%  modes=ceemdan(x,Nstd,NR,MaxIter)
%  [modes its]=ceemdan(x,Nstd,NR,MaxIter)
