I believe that the following code does what you are looking for:
function timertest()
global pos actval
pos = 1;
actval = 0;
n = 5;
del = 5.0;
disp('Start');
t = timer('TimerFcn',@timer_callback_fcn, ...
'Period', del,...
'ExecutionMode','fixedDelay', ...
'TasksToExecute',n, ...
'StopFcn','disp(''Ende'')'); % display 'Ende' when all positions have been printed
start(t);
%disp('Ende'); this will display 'Ende' immediately after start(t), not after all the callbacks have run
end
function timer_callback_fcn(~,~) % you do not use obj or event in your function so it's fine to ignore them
% you do not require any additional parameters (ie. string_arg)
global pos actval;
feld = [1 2 3 4 5];
actval = feld(pos);
pos = pos + 1;
disp(actval);
end
I hope this helps!
