Release notes

Version: beta-0.3.0 (April 2024)​

New features:

  • Network plots allow for interactive editing of the networks.
  • Data-informativity conditions in the predictor model window can be selected to focus on either full network model or single target module estimation.
  • Identification algorithms have been added for single module identification:
    • a non-convex PEM algorithm for the local direct method (Ramaswamy et al, IEEE TAC, 2021), and
    • a sequential convex algorithm for the multistep method of Fonken et al. (CDC, 2023).

Issues fixed since last release:

  • Dependency on MATLAB’s Image Processing Toolbox and Statistics/Machine Learning Toolbox has been removed.
  • Various bug fixes.

NOTE:

  • The Control Systems Toolbox is required to run the App.
