Struct contents reference from a non-struct array object.

Error in pp>pp_OpeningFcn (line 61)
a.arduino ('COM5','uno');

Error in gui_mainfcn (line 220)
    feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in pp (line 42)
    gui_mainfcn(gui_State, varargin{:});

You have

a.arduino ('COM5','uno')

but whatever a is, it is not a structure that has a field or method named arduino

I suspect you might want

a = arduino ('COM5','uno');
