I am having a problem, when I close my GUI, I want all global variables to be cleared so when next time I run program of GUI, everything starts from new inputs.

Assuming you're creating App Designer app (UI Figure-based app), you can set CloseRequestFcn in uifigure. If you're using App Designer, from Comonent Browser, you can add CloseRequestFcn callback.
In this callback definition, add the following to clearall global variables.
clear global
For detail, please read the following document.

For GUIDE GUIs, first add a close request function by opening your GUI in GUIDE, right-click the GUI background figure, and view callbacks. Select "CloseRequestFcn". That will add the close request function to your GUI code.
Then add clear global to the function.
Note that it's better to avoid using global variables altogether. They can cause many problems and you do not need to use them.
