now, i try to control arduino board through Matlab GUI(using IO packages). First,i try to light on the LED by click on the push button i create, below is the callback function i put:
a=arduino('com3')
a.pinMode(10,'output');
a.digitalWrite(10,1);
after i try it, the LED only blink for a second, but now i wish to light on the LED continuously, what code should i type? I wish to light on and light off the LED using push button i create...anyone can help me, thanks..

Disclaimer - I've used Arduinos in the past, but never used the MATLAB Arduino package.
With that said, I'm not sure if this is your issue, but one thing to consider is whether you want your callback to reinitialize the Arduino pinmode every time.
It seems to me like you'd really want to set up the Arduino pin modes and COM ports in the GUI initialization, and then have your callback only perform the digitalWrite.
If using GUIDE, then you will find a GUI initialization function that you can use to do the initialization. Then, you can use the guidata function to add the Arduino object to the guidata. Something like...
a = arduino('com3');
a.pinMode(10,'output');
handles.a = a;
guidata(hObject, handles);
Then, you could use the handles structure again in your callback
handles.a.digitalWrite(10,ledValue)
Again, this is all assuming you are using GUIDE. If you aren't, then you probably know your GUI's initialization better than I do.

Hi Tee,
Are you placing that code in the OpeningFcn?
You may want to have a read through this documentation page, as it discusses data management within a GUI.

Other than that, I can't comment more without seeing your code.
Hope this helps!

You could try using a persistent variable to store that last state, and toggle that each time the callback is fired:
persistent ledValue
if isempty(ledValue)
ledValue = 0;
end
ledValue = ~ledValue; %toggle ledValue
a=arduino('com3');
a.pinMode(10,'output');
a.digitalWrite(10,ledValue);

Apparently digitalWrite doesn't like boolean values - you can make that:
a.digitalWrite(10,double(ledValue));
