CHANGES - Release History of the AMT

Version 1.5.0

General and core functions:
  • amt_start:
    • (Issue #246): Check of the Deep Neural Network package stored in the AMT configuration.
    • (Issue #256): Start-up time improvement by factor three. A complete re-write was required with code parts separation by toolbox installation and toolbox starts. A special starter for the LTFAT (overloading ltfatstart.m) added, needing only a few 100 ms even on Octave. The starter is versioned, with the current support for LTFAT 2.4.0 (October 2018) and LTFAT 2.5.0 (May 2022). For other LTFAT versions, the LTFAT's default starter is used.
    • (Issue #250): Dependency of amt_subdir removed.
    • Octave compatibility improved: io package is obligatory now, handling of packages simplified.
    • Octave compatibility: nan package can be optionally loaded, nanmean and nanstd can be used in Octave now.
  • arg_amt_configuration:
    • (Issue #246): Support for Deep Neural Network package configuration.
    • (Issue #251): Textread replaced by fread because obsolete.
  • Website:
    • (Issue #234): All ° symbols replaced by deg to be parsed in figures correctly.
    • Figures better layouted, now using a table which combines the code, figure, and code output.
    • Distance between the options and their description increased.
  • amt_load:
    • Bug fix for loading files with a blank in the file name.
    • (Issue #272): Time out extended to 10 seconds and the ghosting .html files are removed after the download.
  • amt_extern: Support of empty outputs added.
  • changes (Issue #258): "Description" removed from the documentation.
  • amt_subdir (Issue #250): Removed because of two licenses required and dependencies have been removed.
  • amt_info (Issue #264): Dependence of amt_subdir removed and expanded to work on other files than models only.
  • amt_cache: Bug fix, disp replaced by amt_disp, doc improved.
  • amt_mex: Error on cleaning removed (clean.bat added in /environments).
  • mat2doc (Issue #273): Linking to ghosting figures removed.
  • verhulst2015: Adapted to use amt_extern.
  • eurich2022: Doc fixes, arg_eurich adapted to be AMT compliant.
  • (Issue #259): Now compiles under Octave on Linux.

    • (Issue #263): Fig. 5 is plotted in four separate panels now.
    • (Issue #247): Last row of Fig. 5 seems to be completly wrong, other rows not quite correct. exp_laback2023 refactored for better debugging, but the issue moved to later version.
  • demo_llado2022 (Issue #246): Checks of Deep Neural Network package improved; use cache if package not available; adapted for Octave compatibility.
  • plot_llado2022: Adapted for Octave compatibility.
  • demo_mckenzie2021 (Issue #239): Documentation improved, auxdata adapted to match the publication year .
