DESCRIPTION
i.wavelet Decomposes the time-series with the requested wavelet. The output will have 4 components, High-Pass Level 1 and 2, Low-Pass Level 1 and 2. Low Pass Level 1 can be recomposed using HP2 and LP2 using the recomposition mode.This module is designed to make a temporal fusion from multi-sources.
NOTES
TODO
More wavelet families to be included.SEE ALSO
