The following is a timer that fires at a fixed interval. It's timeout is defined by Period
and it invokes a callback defined by Timerfcn
upon timeout.
t = timer;
t.TasksToExecute = Inf;
t.Period = 0.01; % timeout value in seconds
t.TimerFcn = @(myTimerObj, thisEvent)disp('hello'); % timer callback function
t.ExecutionMode = 'fixedRate';
start(t)
pause(inf);
