%Function for CEEMDAN
%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
% Syntax
%modes=ceemdan(x,Nstd,NR,MaxIter,SNRFlag)
%[modes its]=ceemdan(x,Nstd,NR,MaxIter,SNRFlag)
% Description
%OUTPUT
%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)
%INPUT
%x: signal to decompose
%Nstd: noise standard deviation
%NR: number of realizations
%MaxIter: maximum number of sifting iterations allowed.
%SNRFlag: if equals 1, then the SNR increases for every stage, as in [1].
% If equals 2, then the SNR is the same for all stages, as in [2].

% The current is an improved version, introduced in:
