It seems there is a space between else and if in your code, also we should not provide a logical expression for the else case. These are probably the reason why the methods and functionsare having red underlines.
However, use code below to achieve what you want. (Also, refer to the attached .zip file)
Go to "Fuzzy Button > callbacks > AddButtonPushedFcn callback" and paste the following code
fis = readfis('tipper'); % Read your fis here
i1=app.IP1EditField.Value; % Replace "IP1.EditField" with your field name
i2=app.IP2EditField.Value; % Do the same for all the input & output fields
inputs=[i1 i2];
output = evalfis(inputs,fis); % Evaluate fis, here the output is of type double
% Use appropriate logical expression and linguistic variables as per your need
if output >= 7
app.OPEditField.Value = 'Excellent'; % Note that “OPEditField” is a Edit Field(Text) component
elseif output >= 6
app.OPEditField.Value = 'Good';
else
app.OPEditField.Value = 'Average';
end
Hope this helps!
