Hi, I am just wondering if there is any way to impletment a function like this:

function rslt = example1()
% start call main function
...
try % start followin function, if no feedback within XX seconds, then catch the error
      % call function another thread 
      rslt = callback();
catch
      rslt = 'error!!';
end
...
end

Anyone has an idea?

Thnks

AKAIK: There is no simple way to do that.

We discussed a function, watchdog, in another thread a year ago. I think you could apply the approach of my watchdog_demo. (The conditional break point must be set at an appropriate line in your function, callback.)
