What exactly is "an exe form of the matlab GUI"? What does it mean, that a "GUI has subfolders"? GUIs are the windows on the screen an subfolders are nestes folders on the file system. Please explain, what "takes eternity to run" exactly means. Using the unit seconds is much better that emotional expressions.
As long as it is not clear, where the time is spent, the chances for a matching guess, which solves the problem, are very small.
