ruleedit will be removed in a future release. For more information, see To be removed.


Use the Rule Editor to view or modify the rules of your fuzzy system. To define rules, you must specify the input and output variables of your FIS and their corresponding membership functions.

The Fuzzy Logic Designer app consists of several interactive interfaces for creating a fuzzy inference system (FIS), including the Rule Editor. For more information on interactively creating fuzzy systems, see Build Fuzzy Systems Using Fuzzy Logic Designer.
