Changes

Changelog

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

https://github.com/mstksg/emd/releases/tag/v0.1.1.0

  • Unsized interface added.
