File Information

The Empirical Mode Decomposition is a technique to decompose a given signal into a set of elemental signals called Intrinsic Mode Functions. The Empirical Mode Decomposition is the base of the so-called “Hilbert-Huang Transform” that comprises also a Hilbert Spectral Analysis and an instantaneous frequency computation. A modified improved algorithm for the Empirical Mode Decomposition is implemented. The output is a set of AM/FM modulated signal.
To use it, it is enough to input the signal, two resolutions in dB (~50) and a step value <=1 (normally =1).

I also have this error:
"Debug: Max-Min sequence mismatch.
Debug: Max-Min reverse sequence mismatch."

what does it mean?

hi sir i get error when doing emd on a signal
please send me code of emd

Hi I get the error

"Debug: Max-Min sequence mismatch.
Debug: Max-Min reverse sequence mismatch."

What does this mean?

I am putting in the arguments:

rParabEmd__L(v, 50, 50, 1)

where v = [1,6,2,7,3,8,5,9,5,9,1,3,2,4,3,5,4,6,5,7,6,8,7,9,2,3]

Do you know what I am doing wrong? thanks

Its based on the paper "On the HHT, its problems, and some solutions".

It was tagged as "companion software" by the author, but no link to a book or other package was provided. What is the book or other package to which this is the companion?
