Fuzzy Logic Designer
Design and test fuzzy inference systems
The Fuzzy Logic Designer app lets you design and test fuzzy inference systems for modeling complex system behaviors.
Using this app, you can:
Design Mamdani and Sugeno fuzzy inference systems.
Add or remove input and output variables.
Specify input and output membership functions.
Define fuzzy if-then rules.
Select fuzzy inference functions for:
Adjust input values and view associated fuzzy inference diagrams.
View output surface maps for fuzzy inference systems.
Export fuzzy inference systems to the MATLAB® workspace.
The Fuzzy Logic Designer app does not support type-2 fuzzy systems.
Open the Fuzzy Logic Designer App

Version HistoryIntroduced in R2014b
R2019b: Support for representing fuzzy inference systems as structures will be removed
Warns starting in R2019b
Support for representing fuzzy inference systems as structures will be removed in a future
instead. There are differences between these representations that require updates to your
code. These differences include:
Object property names that differ from the corresponding structure fields.
Objects store text data as strings rather than as character vectors.
Also, all Fuzzy Logic Toolbox™ functions that accepted or returned fuzzy inference systems as structures now
accept and return either
To convert existing fuzzy inference system structures to objects, use the
