I need to use fuzzy logic over several iteration.The output of the first fuzzy iteration will determine the range of the input variable for the next fuzzy logic .

I need to use fuzzy logic over several iteration.The output of the first fuzzy iteration will determine the range of the input variable for the next fuzzy logic .Is there any MATLAB command through which I can dynamically control the range and shape of membership function while the program is running?

Maybe I do not understand your situation, but it seems you can just write some sort of for loop:

%% start

initialization code that constructs fuzzy system FIS and input signals U

Y=evalfis(U,FIS);

%% for loop

for index=1:n,

 FIS.input.range = myfunction(y); % your calculations to update input range
 Y=evalfis(U,FIS);

end

i dont get the range values updated from the excel file. i have the lower and upper limits in the excel file
