  • 0.6.7:

    • refactored the requirements files (add a requirements-dev.txt) and update the documentation (installation) accordingly
    • BUG fixes:
      • correlogram: real-data case had the data flipped
      • pmusic/pev: real-data case had the data flipped
      • fix the AKICc criteria code
    • Updates:
      • pmusic/pev: add the threshold and criteria arguments
      • more tests for the criteria and eigenfre modules
    • Changes:
      • Spectrum class: remove _correlogram method (use pcorrelogram instead)

  • 0.6.6:

  • 0.6.5:

    • minor updates to port spectrum on travis

  • 0.6.4:

    • CHANGES: the bug reported in https://github.com/cokelaer/spectrum/issues/24 is obsolet for the reported module (pburg), which was fixed earlier but the issue was fixed in other module such as psd, parma, correlog
    • add LICENSE file
    • fix warning in cpp code (adding void in func() prototypes)

  • 0.6.3:

  • 0.6.2:
    • Bug Fixes:
      • Issue #11: fixes loading mydpss library using numpy helper
      • Issue #12: Allow loading the shared library for frozen projects. Tested with py2exe.
    • Changes:
      • pmtm returns Sk_complex, weights and eigenvalues instead of just Sk
  • 0.6.1:
    • BUG fixes
      • Issue #5 in pyule sampling not initialised is now fixed
  • 0.6.0:
    • Code moved to github
    • plots accept the ax argument in psd module. It is a bit of a hack but seems to work.

6.4. Sept 2012

  • 0.5.5:
    • fix name of the libraries for mac and windows
    • change setup to manage version properly.

6.5. March 2012

  • 0.5.3: add poly2lsf and lsf2poly, add tests, fix bug related to compilation of mydpss.cc
  • 0.5.2: add pmtm

6.6. 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)

6.7. January 2012

  • 0.4.5: start to play with Pypi

6.8. October 2011

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

6.9. May 2011

6.10. 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
