TypeError with EMD_matlab

[LeonardoLancia]

Describe the bug
the fix for using numpy>=2 introduces a Type Error when using EMD_matlab:

TypeError: unhashable type: 'list'

To Reproduce
from PyEMD import EMD_matlab as EMDm
import numpy as np
x=np.sin(np.linspace(0,24,200))
emdObj = EMDm.EMD()
IMFs=emdObj.emd(x)

Expected behavior
no error is expected here

Running environment
Windows 10, PyEMD version 1.6.2

Thanks for letting me know. It should be fixed now in 1.6.3. Please give it a go, and please let me know if it's actually fixed.

I tried it and could make it work with two furhter (small) changes:

1. comment line 431:
   @staticmethod

2. change line 460 from:

S, T = unify_type(S, T)

to

S, T = unify_types(S, T)

Thank you!

Thanks for testing. EMD_matlab was never really the focus so it was created, tested and left. My bad, there should've been at least regression tests to make sure things aren't broken. Will add these shortly. The typo is embarrassing ^_^

As for commenting @staticmethod... 10 years ago there must have been some reason for it but looking at it now, I don't know why it's there, especially that self is passed as the first argument. I cannot "fix" this now because this might break some people's workflows. However, this should be "resolved" in major version upgrade.

Fix added in 1.6.4 (#166 )
