Not sure what your intent is here...
randperm() only two documented calling syntaxes I'm aware ofone or two arguments. randperm(N) returns 1:N in random order while randperm(N,K) returns K<=N from 1:N
What is the maximum number of questions you have?
I have an initialization call that was
iq=randperm(nMaxQues);
then inside the loop that controls them sotoo
for i=1:length(iq) %display question iq(i)
% break loop logic if any end
I'm not a GUI writer so that part you're on your own...
