I have a question regarding the Fuzzy tool in the Mathlab. In the rule viewer, is there any way to insert many inputs at one time and get the output automatically in the text format or excel format?

For the time being, I have to insert the inputs one at a time to get the calculated output. This is time consuming because I have many inputs to be processed.

Thank you.

Hi. You can use evalfis :

a = newfis('fis1.fis'); %create a new FIS file
a = addvar(a, 'input', 'x', [2 9]);%add and input variable 'x' into the FIS
a = addmf(a, 'input', 1, 'A1', 'trimf', [2 5 8]);%add 2 MFs into the variable x
a = addmf(a, 'input', 1, 'A2', 'trimf', [3 6 9]);
a = addvar(a, 'input', 'y', [4 11]);%add and input variable 'y' into the FIS
a = addmf(a, 'input', 2, 'B1', 'trimf', [5 8 11]);%add 2 MFs into the variable y
a = addmf(a, 'input', 2, 'B2', 'trimf', [4 7 10]);
a = addvar(a, 'output', 'z', [1 9]);%add and output variable 'z' into the FIS
a = addmf(a, 'output', 1, 'C1', 'trimf', [1 4 7]);%add 2 MFs into the variable z
a = addmf(a, 'output', 1, 'C2', 'trimf', [3 6 9]);
rulelist = [1 1 1 1 1;
            -1 2 2 1 1;]; %2 rule is defined and added into FIS
a = addrule(a, rulelist);
writefis(a, 'fis1.fis');
ruleview fis1   
b=readfis('fis1');
% outputs
out1=evalfis([5 8; 6 9; 8 10;3 5;5.5 7.7],b)
