Comparing three files to see what functions were used

I have three mlapps that I need to clean up. They uses some of the same functions in both apps. My task is to figure out what functions are the same in each app, and put it in a single location so that we can manage future changes better.

Is there a good way to do this besides doing a file compare between them?

[John D'Errico]

It is a really bad idea to move MATLAB provided functions around. This will cause problems. DON'T DO THAT.

If it is a question of moving your own functions around, that would be your choice.

not moving matlab functions

I'm not sure it will work for your specific case, but the Dependency Analyzer sounds like it might be helpful.

I have 2022b. which toolbox is Dependency Analyzer in? I don't see it. Is it 2023a only?

@Quy: the linked page that the cyclist gave states "Introduced in R2023a".

See:

Yes, that app is new in R2023a, but I believe much of the underlying funcionality has been around a while. Try a search for some of the key words, such as dependency MATLAB, and you can find some things. Maybe take a look at this older question/answer, too.
