Release Notes

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

  • fix bug in Julia code generation of ZShape and SShape mf
  • disallow implicit conversion from interval to float
  • added semi-elliptic and singleton membership functions
  • added gensurf to plot generating surface
  • fix plotting of systems with several rules and membership functions.
  • fix plotting of Type-2 systems

v0.1.2 – 2023-03-12

view release on GitHub

  • support for weighted rules.
  • allow to specify input and output variables as vectors (e.g. x[1:10]) and support for loops to avoid repetitive code.
  • added support for type-2 membership functions and type-2 systems.
  • added parser for Fuzzy Markup Language.
  • added generation of native Julia code.
  • added left maximum, right maximum and mean of maxima defuzzifiers.

v0.1.1 – 2023-02-25

view release on GitHub

  • Added fuzzy c-means
  • added Lukasiewicz, drastic, nilpotent and Hamacher T-norms and corresponding S-norms.
  • dont build anonymous functions during mamdani inference, but evaluate output directly. Now defuzzifiers don't take a function as input, but an array.
  • added piecewise linear membership function
  • added parser for Fuzzy Control Language and matlab fis.
