It appears that it is possible. You need to take some steps to save the generated sketch before hand. Then you can have your GUI send the sketch to the device in order to start it running. See
I have not investigated arduino enough to know how to remotely control it to stop a sketch running afterwards.
Depending on your purposes, you might find it easier to instead have the sketch already loaded (e.g., use the tools to prepare and automatically upload it), but to have it programmed to wait for input before it proceeds with its main purpose.

Cheers for the link. It's clear I need to clean up that solution and maybe make a a little program for the community.
With regards to stopping a sketch:
Presumably a serial connection is involved. If it is, then some Arduino's will stop on their own when the serial connection has been terminated on the PC end. This can be good or bad. Seems to occur with the Inland Arduino's from Microcenter.
However what I rely on is sending serial commands to the Arduino. In your Arduino sketch, you just need to add to your loop a quick check to see if there is anything in the serial buffer. If there is, read it and parse it. If it has your "start" or "stop" command, you react accordingly. It would be best if you are changing the run state, not a hard command. Then in your Arduino loop you can have
void loop()
{
readSerial()
if runMode == 1
// Your run code, one loop
else
// Delay to not tax the Arduino too much
delay(100)
end
} // end of void loop()

Just search the forum for arduino by clicking the tag above.

Sorry, no. I have an arduino but I haven't found time to play around with it in MATLAB yet.
