Hello.

I have 2 GUIs (figure1 and figure2). I pass 1 data from figure1 to figure2 via a pushbutton in figure1. The input is a double type.

function pushbutton4_Callback(hObject, eventdata, handles)
figure2({input})

In figure2 opening function, I have

function figure2_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA) 
% varargin   command line arguments to figure2 (see VARARGIN)
% Choose default command line output for figure2
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
% UIWAIT makes figure2 wait for user response (see UIRESUME)
% uiwait(handles.figure2);
stageNo = varargin{1};

In figure2, I also created a pushbutton to close figure2 after storing some data.

function cancelbutton_Callback(hObject, eventdata, handles)
user_response = modaldlg1('Title','Confirm Close');
switch user_response
case {'No'}
case 'Yes'
close(figure2)
end

However, everytime I click the cancelbutton, figure2 pops up again and gives me error:

Index exceeds matrix dimensions.
Error in protA_select2>protA_select2_OpeningFcn (line 68)
stageNo = varargin{1};
Error in gui_mainfcn (line 220)
  feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});
Error in figure2 (line 40)
  [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
Error in figure2>cancelbutton_Callback (line 690)
close(figure2)
Error in gui_mainfcn (line 95)
  feval(varargin{:});
Error in protA_select2 (line 42)
  gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)figure2('cancelbutton_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback

Anyone ever experience this before?

I make the GUI via guide and for some reasons, I need to pass the input without setappdata.

Thanks a lot! :)

'figure2' is not defined in that scope.

I assume you want to use

handles.figure2

as the handle of your GUI to close.

Hello, Adam! Thanks for your help!

Usually I write

close(name)

to close the figure. In this case, the name is figure2. Does it have to do with the tag name? Because I just tried your suggestion with

close(handles.tag)

and it works.

I have another gui file made in GUIDE that works also with only close(filename). However, this particular file does not have input argument. Thanks a lot anyway! :)
