How to find IMF's using EEMD (Ensemble Empirical Mode Decomposition), CEEMD (Complete Ensemble Empirical Mode Decomposition), VMD(Variational mode decomposition), MEMD(Multivariate Empirical Mode Decomposition) in the following Synthetic signal?
Fs=500;
dt=1/Fs;
t = 0:(1/Fs):2;
x1 = 0.7*sin(2*pi*8*t);
x2 = 0.7*sin(2*pi*24*t);
x3 = 1.4*sin(2*pi*30*t);
x = x1+x2+x3;

Hi Tejas,
I understand that you want to find Intrinsic Mode Function's using EEMD, CEEMD, VMD and MEMD.
The 'IMF' can be found using Empirical Mode Decomposition
imf = emd(x)
The 'IMF' can also be found using Variational Mode Decomposition
imf = vmd(x)
Unfortunately, there are no MATLAB functions to compute 'IMF' using EEMD, CEEMD and MEMD.
I hope the above information resolves your query.
