I am doing serial communication between matlab and controller. I have created a GUI. The problem is whenever I am starting serial communication the GUI doesn't appears but when I terminate the program GUI appears. I want GUI to appear in real time.I am not getting the problem.

Create serial object BytesAvailableFcn callbacks to handle the serial data, instead of looping around checking for data.
There is a sample GUI for serial communications in the File Exchange

It would seem to make the most sense to put the display code in pushbutton1_Callback, or at least have pushbutton1_Callback call the display code.
Note: fgets() returns the line terminator as part of the string, but you are using == to do comparisons. You should use fgetl() and you should use strcmp()
