Procedure to perform EEMD in Matlab

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)

For more information, refer to the 'emd' and 'vmd' documentation pages.

Unfortunately, there are no MATLAB functions to compute 'IMF' using EEMD, CEEMD and MEMD.

I hope the above information resolves your query.

Thank you so much for your kind reply.
