I am trying to devise a Sugeno fuzzy system using the fuzzy GUI - for some reason when I add more than one output variable I get errors:
Error using length
Too many input arguments.
Error in addvar (line 76)
for ct=1:length(out.output.mf)
Error in fuzzy (line 746)
fis=addvar(fis,varType,'',[0 1],'init');
Error while evaluating uimenu Callback
I'm using 2014a on a Mac running Mavericks. To note, I also have 2013a installed on a MacBook and tried adding the same input and output variables and I get them same error messages.
If you add more than one output variable, then try and add an input variable the above messages are then displayed within the command prompt.

What does out.output.mf return? Put a breakpoint at the line
for ct=1:length(out.output.mf)
and run your code. When the debugger pauses at this line, in the Command Window type
out.output.mf
What do you see? The error message is suggesting that too many input parameters are being passed to the function length so check to see what is being passed to this function.

This is a bug that is to be fixed in a future release. As a workaround, add the second input first and the second output afterwards.
