SyFSeL is a free open-source library that automatically generates synthetic fuzzy sets. It is aimed for use in empirically testing methods developed for fuzzy sets. SyFSeL generates as many sets as desired, with specified membership function type (normal, bi-modal or multi-modal) and fuzzy set type (type-1 or type-2) to enable users to emulate real data. Fuzzy sets are stored in csv format so users can easily import the generated sets into their own fuzzy systems software and SyFSeL can also create graphical plots of the generated sets.
The library is available through the software page of the LUCID website and is available here.
For more information on the library and how to use it, see the related paper here.
