Hi @muhammad

If you are sure that the Fuzzy Logic Toolbox is installed but its functions are inaccessible, the issue is most likely related to licensing. Run the following commands to check whether the Fuzzy Logic Toolbox license is functioning correctly. If the license is valid, the commands will return 1. Otherwise, they will return 0.

license checkout Fuzzy_Toolbox

ans = 1

license('test', 'Fuzzy_Toolbox')

ans = 1

If you need further assistance, please contact MathWorks Account and Licensing for technical support: https://www.mathworks.com/support/contact_us.html

If you wish to design a lightweight fuzzy system, it is perfectly acceptable to implement it mathematically in MATLAB without using the Fuzzy Logic Toolbox.
