I want to move an analysis pipeline from Matlab to Python. I'm noticing a slight difference between the IMFs generated by the emd function in Matlab and those created by the emd.sift.sift function for Python. Specifically, I'm calling:

imf = emd(signal,'SiftRelativeTolerance',0.1,'MaxNumIMF',4) #matlab
imf = emd.sift.sift(signal, sift_thresh=0.1, max_imfs=4) #python

And obtain the following IMFs: enter image description here

Comparing the two functions, I can't really figure out what may be driving the difference. Does anyone know what may be causing this (and how to fix it)?
