Changelog

Version 0.1.8.0

October 4, 2019

https://github.com/mstksg/emd/releases/tag/v0.1.8.0

• Add meanMarginal

• Fix degreeOfStationarity for divide-by-zero errors.

• Add foldFreq for generalized folding on HHT, and rewrote other functions in terms of it.

• Drop support for GHC 8.2 and lower.

• 0.1.8.1: Exported marginal again; it was unexported by mistake.

Version 0.1.7.0

September 24, 2019

https://github.com/mstksg/emd/releases/tag/v0.1.7.0

• Rewrite hilbert using the fft library, matching the matlab implementation. This means that the library now depends on fftw.

Version 0.1.6.0

September 24, 2019

https://github.com/mstksg/emd/releases/tag/v0.1.6.0

• Add hilbertPhase to Numeric.HHT.

Version 0.1.5.1

September 3, 2019

https://github.com/mstksg/emd/releases/tag/v0.1.5.1

• Remove dependency on pure-fft, using statistics instead.

Version 0.1.5.0

August 31, 2019

https://github.com/mstksg/emd/releases/tag/v0.1.5.0

• Add NFData instance for EMD, HHTLine, and HTT
• Add iemd, inverting emd.

Version 0.1.4.0

August 20, 2018

https://github.com/mstksg/emd/releases/tag/v0.1.4.0

• hhtSparseSpectrum added to Numeric.HHT module, for an alternate sparser representation of the Hilbert Spectrum.
• hhtDenseSpectrum also added to Numeric.HHT, for an alternative denser representation.
• expectedFrequency added to Numeric.HHT module, to calculate weighted average of frequency contributions at each step in time.
• dominantFrequency also added to Numeric.HHT to calculate strongest frequency at each step in time.

Version 0.1.3.0

August 15, 2018

https://github.com/mstksg/emd/releases/tag/v0.1.3.0

• Default instance for SiftCondition and EMDOpts, as a useful alternative to defaultEO and defaultSC for those who prefer it.
• Binary instances for EMD, HHT, and related data types. These are based on Binary instance for v a, so the user must bring the orphan instance of their choice into scope. Not sure if this is the best way to do this.

Version 0.1.2.1

July 27, 2018

https://github.com/mstksg/emd/releases/tag/v0.1.2.1

• BUG FIX Fixed behavior of frequency wrapping to wrap between 0 and 1, instead of 0.5, as claimed!

Version 0.1.2.0

July 27, 2018

https://github.com/mstksg/emd/releases/tag/v0.1.2.0

• Actually implemented the Hilbert-Huang transform
• Allowed for other border handling behaviors during EMD
• Changed default stopping conditions for sifting process
• Added clamped spline end conditions.
• Removed unsized interface
• Sifting will now throw runtime exception for singular splining matrices, instead of treating the result as a residual. This might change in the future.

Version 0.1.1.0

July 25, 2018
