Providing you’re not using the ‘index’ and ‘sort_user1’ variables elsewhere, try:
for i = 1:no_users
[index, sort_user1] = singleuser_traffic(num_event);
indexes(:,i) = index;
users_data(i,:) = sort_user1;
end
This doesn’t significantly add to the overload, and will let you see what the incompatibility is between what the function returns and what you want in your ‘indices’ and ‘users_data’ arrays.
I’ve found that for whatever reason, most functions will crash if you ask them to fill arrays for you. Let them return what they want, and do the array assignments just after.
BTW, num_event isn’t subscripted in your loop, so unless you’re defining it to change outside the loop you posted, you’re giving it the same argument in each iteration.
