Why are you using a script for anything serious? You should be using functions instead, as those provide a stable interface.

You can absolutely call a function from within a function. So you don't need to use a script at any point.

In the function where you are computing the result, copy it to main workspace using eval(). e.g. if result is a scalar, eval(['result=' num2str(result)]). This would make the variable available in main workspace. Another way is to use global variables.

Note that both these are less efficient ways of dealing with variable scopes.

How are you calling your function? It sounds like you should set that variable as the output argument of your function.

You should not need eval or global. There are almost always better ways.

You should edit your function so you can actually retrieve the output and call it like this:

% Button pushed function: ResultButton
function ResultButtonPushed(app, event)
    Result = TestPenchCode3;   %calling function
    app.EditField.Value = Result;
end

You never need to use eval.
