Regeneration of signal using different Intrinsic Mode Function Components.

I am facing difficulty in how to recreate the original signal again by using 3,4 or 5 or more Intrinsic Mode Fucntion components ? Please guide me.

The original signal is the sum of Intrinsic Mode Functions (IMFs) and the last residue ():

To obtain accurate results, the key is to add the residue term to the IMFs. Use the “emd” function to store the IMFs and residue from the original signal in variables which can later be used to reconstruct the signal.
