I did not know anything about this, so I sent it to Tech Support (www.mathworks.com/support)

Java does not halt MATLAB timers. Is there a reproducible example where this behavior does occur?

Doug

Like your blog! Reading this post I figured it should be possible to use a timer to monitor the size of file (with the purpose of updating a progress bar).

And indeed it works fine, except…

When I am monitoring a file that is being retrieved through ‘mget’ (== java ‘retrieveFile’).

It seems the java call halts all matlab timers… Can that be true?

Thanks,
Dennis

There are not enough details here for me to help you. Please contact me with more specific questions, and an example of code you have tried.

-Thanks,

I am confused about TimerFcn. I am trying to GUI that can refresh data every second but i didn’t understand how to implement subroutine when timerFcn execute. Where and how i should write that?

thanks

I think you are best served with technical support:

They should be able to help very quickly.

I posted the following questions below in the user community, but nobody has responded…I then found this discussion…Any ideas?–>

“I am posting this to see if anybody has had similar problems
with 2007b or later (when Matlab became multithreaded)…

I execute this code in the interpretor:

>>t = timer(’Period’, 1, ‘timerfcn’, ‘disp(”hello”)’,…
‘executionmode’, ‘fixeddelay’, ‘busymode’, ‘error’);
>>start(t);

The callback occurs a few times (I say “a few” because it
could be 1, 5 or 10034, there does not seem to be any reason
to it), and the appears to get “lost”. When I query the
timer, it claims that is is running, however it has stopped
callback execution. I do a lot of process control and have
used timers quite extensively in earlier versions of MATLAB
and have never had this problem. Any ideas?

Note: When I change the number of maximum number of computational threads to 1, the timer callback seems to behave just fine…I however need to use the multiple threads in my application.”

Our doc can explain this much better than I can.

It almost sounds to me like you would be better off using Simulink for the simulation you are running. With all of the time dependencies you are working with Simulink and its constant marching of time would probably be better.
