starting, stopping and waitFor in a timer

I need to start a timer and then block the MATLAB command line. In the background when a certain callback executes, I need to restart the timer and also block the MATLAB

I tried, but the code below does not work:

x=timer('Name','maxtimeBetweenEvents','StartDelay',20,'Timerfcn','a=1');
start(y);
start(x);

waitfor(x);

delete(x);

function restartTimerBetweenEvents
eventTimer=timerfind('Name','maxtimeBetweenEvents');
stop(eventTimer);
start(eventTimer);
waitfor(eventTimer);
end

I am not exactly sure what you want - but I think this is close.

1. Creating a timer that blocks the MATLAB command line for a certain time.

%% Create a timer
t = timer('Name','maxtimeBetweenEvents','StartDelay',30,'TimerFcn',@(x,y)disp('Hello World!'),'Tag','Waiting');

%% Start a timer

start(t)

%% Start your waiting 

wait(t)
disp('The wait is over!')

2. To restart the timer.

start(t)
wait(t)
disp('The wait is over!')
