Global Variables. Migrate code from MatLab

[micseydel]

You can give me a short example from what you mean with "import the variable into the other file"? It's different from use arguments into functions?

They are different, but looking more closely, you can't do it because the files would have to import from each other.

Is I a variable or a constant? Things are hairy if it's a variable. If it's just a constant, you can keep it in a separate file for constants if it's needed by multiple things (or needs to be easy to change) and if it's just needed in one place, that's probably where it should live unless there's a good reason to put it somewhere else.
