Hi,
I have the following code: ( I am not sure why the code is not working but I am using a modern version of matlab and the code was written for an older version of matlab), your help will be greatly appreciated!
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});
the error that it gives is the following:
Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure),
varargin{:});

There should have been more to the error message, saying what MATLAB thinks is wrong.

The whole error message looks something like this: (there isn't more to the error message for some reason)
Warning: The JavaFrame figure property will be removed in a future release. For

Apparently what you are asking to do is not permitted by Java.
But you might possibly be able to Undecorate the window.
