Answer 1

[Walter Roberson]

Your playerse1 is not a FIS structure.

[Anagha Bhattacharya]

I had created that fis structure with that name

[Walter Roberson]

How did you create it?

hello guys. I need help with this error too:

Given FIS fiss is unknown.

Error using evalfismex

Exiting ...

Error in evalfis (line 83)

[output,IRR,ORR,ARR] = evalfismex(input, fis, numofpoints);

Error in fuzzm (line 98)

SS = evalfis([output],fis);

I creat my fiss with this code without using fuzzy interfence

fisname='fuzzychaos';

fistype='Sugeno';

andmethod='min';

ormethod='max';

impmethod='prod';

aggmethod='probor';

defuzzmethod='wtaver';

fis= newfis('fuzzychaos','Sugeno','min','max','prod','probor','wtaver');

%......................input...........................................

fis=addvar(fis,'input','A1',[0 255]);

fis=addmf(fis,'input',1,'L','trimf',[0 95 105]);

fis=addmf(fis,'input',1,'C','trimf',[105 125 155]);

fis=addmf(fis,'input',1,'R','trimf',[160 195 255]);

fis=addvar(fis,'input','A2',[0 255]);...................

I created rest of the code with (addrule and writefis,and read fis for reading what I created and I don't know if it works or not but it seems it does'nt)

please help me

thank you very much
