Which userfcn do you provide? You have to insert changes there, so please post the code of your userfcn.
It should start with
function [output1, output2] = theNameOfYourFcn()

userFG shall return one or two arguments. You can see that the code tries to call userFG and retrieves two returns. If this call throws an exception, then it tries to call userFG and retrieve one retuen. If this also throws exception, then it errors out. So it expects one or two returns.
