I was using the Fuzzy Logic Toolbox in my implementation but now I'm trying to modify the membership functions in my system, tunning?  I'm using ,newfis, addvar, addmf, writefis, in matlab to implement the functionalities presented in the Toolboox.

I'm kinda new with Matlab and i know that is possible to implement code in simulink using the Matlab Function block but I'm having some problems with this. Has Someone implemented something like this? or have an idea would be great.
