Hi,
I have a GUI set up, but i want to use the input from this data in a seperate function (called 'Atps') which is not my main. Is there a way i can get the variable out of the GUI function and into Atps?
Thanks in advance

You can access all your GUI components by their tags. It will be different depending how you created the GUI. But e.g. in GUIDE you can put
param1 = str2double( get( handles.editParam1, 'String' ) );
param2 = get( handles.sliderParam2, 'Value' );
etc
in a 'Run' button callback, which you create just by adding a button and going to its callback.
Then you call your function as you would from anywhere else once you have its inputs, e.g.
Atps( param1, param2 )
or whatever you need to pass in.

Thank you for your reply, I get the error message "Dot indexing is not supported for variables of this type" when using this, is there any way to solve it?

It depends where you are getting the error and on what. The only place I use dot indexing above is on handles, which, if you are in a callback in GUIDE, should be a struct. If you aren't in GUIDE then you need to get hold of your components in a different way.
