7. ChangeLog Summary

7.1. March 2012

• 0.5.2: add pmtm

7.2. February 2012

• 0.5.1: add dpss wtapering windows

• 0.5.0:

  • NPSD replaced by NFFT (qlso not correct for ARMA methods that do not have NFFT since not fourier)
  • Correlogram replaced by pcorrelogram
  • more consistent function and class naming convention
  • Update the entire documentation.

• 0.4.6: fixed pylab_periodogram, documentation (installation)

7.3. January 2012

• 0.4.5: start to play with Pypi

7.4. October 2011

• 0.4.4: Start to provide the library on the web www.assembla.com

7.5. May 2011

• 0.4.3: spectrum.periodogram.pdaniell() implemented

7.6. April 2011

• 0.4.2: pcovar implemented
• 0.4.1: pmodcovar implemented
• 0.4.0: arcovar and modcovar “simplified” version. Documentation updated (tutorial, spectral_estimation, quick start...)
• 0.3.19: add linear_prediction module with codecs (eg. ac2poly, poly2rc....)
• 0.3.18 fix bug in levinson (Real data case only) and add ac2poly function.
• 0.3.17: validation of the modcovar algorithm versus the new arcovar_simplified function.
• 0.3.16: add a simplified version of arcovar called arcovar_simplified. It is 10 times faster and with a different algorithm provides the same results as arcoar, which validates the two codes!
• 0.3.15: add corrmtx function. Tested it within music algorithm
• 0.3.14: cleanup the eigen and music methods by moving the automatic order selection outside the functions.
• 0.3.13: Add AIC and MDL criteria to deal with automatic eigen values selection in pmusic and pev
• 0.3.12: test and validate the pmusic and pev pseudo spectrum.
• 0.3.11: burg and pburg finalised
• 0.3.10: tools module cleanup and finalised
• 0.3.9: ma fully checked and add pma validated
• 0.3.8: minvar fully checked and add pminvar
• 0.3.7: aryule fully checked and add pyule
• 0.3.6: Speed up by 3 the ARMPSD (renamed to arma2psd)
• 0.3.5: refactoring
• 0.3.4: fix all tests and doctests
• 0.3.3: function Daniell’s periodogram implemented in module periodogram
• 0.3.2: Create class MovingAverage, pburg, pARMA, Correlogram, Periodogram, Minvar, pma
• 0.3.1: Cleanup MA, ARMA, BURG, MINVAR
• 0.3.0: Create an ABC class Spectrum, a FourierSpectrum and ParametricSpectrum.
• 0.2.4: Finalise doc/test of the testdata module
• 0.2.3: define a PSD class
• 0.2.2: cleanup cholesky.py
• 0.2.1: a new sphinx layout,
• 0.2.0: correlogram.py, correlation.py, levinson.py fully completed

7.7. March 2011

• 22th March 2011:

  • put this doc online on thomas-cokelaer.info (fixed main links)

• 21th March 2011:

  • create psd.py defines useful class to manage Spectrum/plot
  • periodogram.py has a simple periodogram implementation equivalent to psd in pylab without overlaping.

• 7th March 2011:

  • add periodogram module
  • fix ARMA method in arma module

• 4th March 2011:

  • Create first revision of spectrum package
