%EMDC_FIX  computes Empirical Mode Decomposition%%%   Syntax%%% [IMF,NB_ITERATIONS]=EMDC_FIX(T,X,NB_ITERATONS,MAX_IMFS);%%%   Description%%% computes EMD according to [1] with NB_ITERATONS sifting iterations for each IMF%%   mean of boolean array {(mean_amplitude)/(envelope_amplitude) > THRESHOLD} < TOLERANCE%   &%   |#zeros-#extrema|<=1%% inputs:	%       - T: sampling times. If T=[], the signal is assumed uniformly sampled.%       - X: analyzed signal%       - NB_ITERATIONS: number of sifting iterations to be performed to%         extract each IMF. If NB_ITERATIONS is empty or unspecified, 10 iterations %         are performed by default.%         Note: The effective number of sifting iterations might be less %         than NB_ITERATIONS for the last modes if the sifting process has %         to be stopped because of a lack of extrema.%       - MAX_IMFS: maximum number of IMFs to be extracted. If MAX_IMFS is%         zero, empty or unspecified, the default behavior is to extract as%         many IMFs as possible.%         % outputs: %		- IMF: intrinsic mode functions (IMFs) (last line = residual)%		- NB_ITERATIONS: effective number of sifting iterations for each mode%%%   Examples%%% workspace: %  T: 1xN time instants%  X: 1xN signal data %%>>IMF = EMDC_FIX(T,X);%>>[IMF,NB_IT] = EMDC_FIX([],X);%>>IMF = EMDC_FIX(T,X,0.1);%>>IMF = EMDC_FIX(T,X,[0.1,0.1]);%>>[IMF,NB_IT] = EMDC_FIX([],X,[],4);%%%   References%%% [1] N.
