How can i speed up the working of GUI???

I have created a GUI to control a robot for going forward,backwadr.left and right. But the speed at which gui works is very slow.The robot gets the command around 2 mins after the button in GUI is pressed.Please help me to speed up the interfacing because time precision is very important in controlling the bot. I am using atmega16 to interface the gui with robot.

Without knowing any details it is impossible to guess, what happens. You have to find out at first, where the delay is comming from: Is it really Matlab or a problem in the hardware interface?

hardware is fine because when i use serial interfacing without GUI, the speen is good.....bt usinf GUI lowers the speed...

Please define speen, bt, and usinf - or else use a browser with a spellchecker.

@Image Analyst: speeD and usinG. The spell checkers make me nervous, because I post in different languages and cannot find a way to toggle the language easily.

You have to start the profiler, run your application and inspect the profile report afterwards. See doc profile .
