Display GUIDE GUIs in random order?

I have 14 GUIDE GUI's and I want them to appear in a random order, one after another.

i.e. GUIDE GUI #1 opens, press push button and then the next GUIDE GUI pops up (e.g. GUIDE GUI #2) and GUIDE GUI #1 closes. The next GUIDE GUI that comes is random (one of the 13 that remain)

How may I about doing that?

Any relevant input would be greatly appreciated.

Assuming you mean a pushbutton on some separate controlling GUI rather than on the GUI just opened, the the OpeningFcn you can define:

handles.guideGUIs{1} = @GuideGui1;
handles.guideGUIs{2} = @GuideGui2;
...
handles.guideGUIs{14} = @GuideGui14;

handles.hGUI = [];

then in the pushbutton's callback you can have something like:

delete( handles.hGUI );

r = randi( numel( handles.guideGUIs ) );

handles.hGUI = handles.guideGUIs{r}();

handles.guideGUIs(r) = [];

guidata( hObject, handles );

That is meant as a framework rather than something that will necessarily work exactly if you paste it in - I wrote it off the top of my head so haven't actually created a GUI to test it out (though I did test the function handle launching).

I implemented this in the code and it works (Thank you Adam), however how do I remove a GUI that has already appeared among the 14?

When the push button is pressed, the GUI in which that push button is pressed should be removed from the randomised set of GUIs. How though ...

[Adam]

handles.guideGUIs(r) = [];

should do that.

[Muaaman]

I stored handles.guideGUI as a global variable in a .mat file called varDatabase.mat.

I then have in the pushbutton Fcn:

dbedit = matfile('varDatabase.mat', 'Writable', true);
handles = dbedit.handles;
delete(gcf)
handles.hGUI = [];
delete( handles.hGUI );
r = randi( numel( handles.guideGUI) );
handles.hGUI = handles.guideGUI{r}();
handles.guideGUI(r) = [];
guidata(hObject, handles);

When I run this, it proceeds to the next randomized GUI however it gives this error:

Error using guidata (line 89)
H must be the handle to a figure or figure descendent.

Error in arq_01>pushbutton1_Callback (line 147)
guidata(hObject, handles);

Error in gui_mainfcn (line 96)
        feval(varargin{:});

    gui_mainfcn(gui_State, varargin{:});

Error in
@(hObject,eventdata)arq_01('pushbutton1_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

Input regarding how to resolve this issue would be appreciated.

The

guidata( hObject, handles )

line assumes this is all going in a GUIDE-based GUI with a pushbutton in it.

If that is the case then there shouldn't be any saving to mat files needed. The handles structure is part of the GUI, you should never load in a handles structure from file in a GUI.

If it isn't run from a GUI then you don't need guidata and probably shouldn't name the structure 'handles'.

And how to do it, if we assume the button is in the GUI just opened? Like you have a GUI that is the one where you insert basic information, then you click start and it launches the first GUI, then this just opened GUI will have a "continue" button that closes this GUI and open another one, that will have another "continue" button and so on
