By GUI I can get them but I want to get them by a function or command or ....

Hello Ghazal,

Follow this procedure:

- first load the Fuzzy file by using the command:

fis = loadfis ('fuzzyfilename')

Replace fuzzyfilename with the name you saved your fuzzy file with. The quotes are not removed.

- for instance, if your system is a 2 inputs, 1 output system, then use this command to get an output value for two input values:

Output = evalfis (fis, [inputvalue1 inputvalue2])

Simply replace 'inputvalue1' and 'inputvalue2' with numerical values, the result would be a numerical value of the output based on your rule-base.

Hope this is what you're looking for?

Best Regards.

thanks for your answer;

i've tried loadfis but it didn't work so i choose readfis instead.

fis=readfis('file name');

out=evalfis(input value,fis)

but the result was the same however i changed the value of the input

It's actually readfis. Apologies for the error.

If you're getting the same result, it could probably be because of your membership function type and range. Also, remember that the input values are placed in a square bracket [ ].
