Execute a code section with a button

Hello,

I have multiple code sections in my m-file separated with the double %% sign. Each code section outputs a plot. Now I want to create a GUI with multiple buttons for each plot. How can I program that a button executes a certain section?

Just move the relevant sections of code into callback functions for the buttons, or better still, into standalone functions that are called from the callbacks and could also be called from anywhere else if desired too.

But then I have the problem that my variables are in the local workspaces and the functions can not share them.

Yes ok so I can share data between functions. But my problem is that I have a simulink model which outputs data in the workspace. Then one section of my program reads and process the data, the next one calculates some values for the plots and the other sections plot the data into multiple diagrams. But meanwhile the program is so big that I want to split it into several parts.

What is the easiest way to do that?

I'm afraid I know nothing about how Simulink works with workspaces as I have never used it so I'll have to leave that to someone else. /breaking data into functions and passing in only the variables the function itself needs is usually the best way to break down a large program though, or use OOP to create classes, but that is rather more advanced, though does solve problems of sharing data between multiple workspaces more neatly.
