Error of Display Image that has highest psnr value in exe file but not in matlab file

This is a code for push button to display image that have highest performance value based on psnr. So, I have make if else statement to display the best of image enhancement. The problem was, when I execute file in .exe its not display the image but in matlab file its display with no error

Why are you using a global variable? The handles struct is right there to store this kind of data.

You also forgot to format the question and describe your problem.

I already update my code and describe my problem. Im sorry if Im confusing you just now.

15 global variables and 4 words worth of comments. How do you expect people to understand what you want to do? Why are you using global variables with such short names?

What you can do is to set a value to a uicontrol text box. That way you can keep track of which lines are executed without the debugging tools being available.
