How can I make this code a function to extract data and use the data in another code?

Why not just save whatever data you want in a .mat file that the other code can load?

I would use the refactor button. See here: https://www.mathworks.com/videos/convert-code-to-reusable-functions-using-the-refactor-button-in-matlab-1680849938557.html

I tried to but it is telling me: selection must not be inside a loop

[Cris LaPierre]

Which lines of code are you wanting to be a separate function? And what data should it return?
