信号分解CEEMDAN算法（ceemdan.m）

代码说明：

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)%%--------------------------------------------------------------------------% This algorithm was presented at ICASSP 2011, Prague, Czech Republic% Plese, if you use this code in your work, please cite the paper where the% algorithm was first presented.
