How do I access AppDesigner variables in a function that I write and call?

I am calling a function that I wrote from a GUI I designed with Appdesigner. I want to use many variables such as app.* in that function. I would rather not define a huge number of input variables for the function. I have used global variables in the past, use of global variables is not recommended by Matlab and teh global declaration gets a forbidding red underline. Is there an easy and compact way to access all the app.* variables functions called by the GUI designed in appdesigner?

So, if I call the function with "app" as an argument, as if "app" is a structure, I should be able to refer to all the variables that are defined in the Appdesigner code as app.var1, app.var2.... etc within the function?

You can also call any public methods of app, so if your app had a public function, myAppFun
function result = myAppFun(app,x)
...
end
then inside of your function, myFun that takes app as an argument you could call it using for example
function myFun(app,x)
y = app.myAppFun(x)

So I'm understanding that you have written a function and want to call it from within your appdesigner app. You then want this function to have access to the variables within the app. If so, I think you can get what you want simply by passing app as an argument to your function.
