selstruc(): How to avoid hitting "Return" in command window?

I'm building a little App (.mlapp) for System Identification based on this example: https://www.mathworks.com/help/ident/gs/identify-linear-models-using-the-command-line.html

I'm using selstruc(arxstruc(...)) to estimate model parameter but after selection, it's not sufficient to close with the "Close" button, but I have to switch to main Matlab command window and hit return, as mentioned in the dialog.

Is there any way to avoid this and continue directly after pressing "Close"?

Hi Alexander,

I don't think there is a way to avoid that, this is the current APP behavior.

The only thing I can think of is to avoid using GUI and rely on command line to select order automatically.

% V is output from arxstruc or ivstruc
order = selstruc(V,c);      % c is a number 
order = selstruc(V,'aic');
order = selstruc(V,'mdl');
