You cannot create a GUI for that code unless you get rid of the "clear all", as "clear all" would instruct MATLAB to remove everything *including* the GUI.

Please format your code and ask a specific question. Showing a program and asking for a general GUI is to vague to be answered specifically. So what kind of help do you expect?

It is more likely, that you get a useful answer, if you ask a specific question. Currently it is not clear which kind of help you expect. It is unlikely that a contributor will implement this for you, and if anybody does, it is unlikely that it matchs your needs exactly.

I suggest that you try to create the GUI by your own at first and come back with explicit questions on demand.

Look in the FEX for "41 sample GUI"

Think twice before you overwrite the contents of your question. Afterwards the given answers are meaningless and the persons, who have spent time for answering will hesitate to help you for other problems in the future.
