How should I look at res or rn ? your examples do not show the resulits

Please elaborate on your question. Do you mean to plot residue?

Yes，many tools show that the last graph is residual part.Your examples do not show the residue

Sorry, I thought there were information about this issue. It's a rather common question. Will update the code and possibly provide some quick library on how to display on the weekend.

For now please use these:

import pylab as plt
from EMD import EMD

# S is your signal

imfs = EMD(S)
res = imfs[-1]
plt.plot(res)
plt.show()

Thanks.Although the last graph is imfn，actually it is residual part. Do I understand that correctly?

If there is a residual it will be the last component in the imfs results. You can also use get_imfs_and_residue() method in EMD instance which will return separate imfs and residue.

import pylab as plt
from EMD import EMD

# S is your signal

emd = EMD()
emd.emd(S)
imfs, residue = emd.get_imfs_and_residue()
plt.plot(residue)
plt.show()

Also, I just (38b2cc39e9f532ea436da0fea673916c3c449b8f) added Visualisation module which should help with displaying the results.

Please check Readme for an example.
