"The ensemble empirical mode decomposition (EEMD) and its complete
variant (CEEMDAN) are adaptive, noise-assisted data analysis methods
that improve on the ordinary empirical mode decomposition (EMD). All
these methods decompose possibly nonlinear and/or nonstationary time
series data into a finite amount of components separated by
instantaneous frequencies. This decomposition provides a powerful method
to look into the different processes behind a given time series data,
and provides a way to separate short time-scale events from a general
trend. We present a free software implementation of EMD, EEMD and
CEEMDAN and give an overview of the EMD methodology and the algorithms
used in the decomposition. We release our implementation, libeemd,
with the aim of providing a user-friendly, fast, stable,
well-documented and easily extensible EEMD library for anyone interested
in using (E)EMD in the analysis of time series data. While written in C
for numerical efficiency, our implementation includes interfaces to the
Python and R languages, and interfaces to other languages are
straightforward."
