i want to set handles for an array of pushbuttons starting from pushbutton1 to pushbutton10 (i.e. pushbutton(i)), is this possible in Matlab? for example a code look like
for i=1:10
set(handles.pushbuttton(i),'String','i')
end
thanks..

What happens when you run the code and what do you expect to get? You probably want to replace 'i' with num2str(i).

This code doesn't work... briefly, i have 300 buttons in my GUI and i made this Gui by GUIDE, i need to save the states of these buttons(i.e.backgroundcolors), but i cannot do it each time like "state.pushbutton1=get(handles.pushbutton1,'Backgroundcolor'); " for 300 buttons, therefore i need to make an array for which i need to write "state.allpushbuttons=get(handles.allpushbuttons,'Backgroundcolor'); "
could i explain it clear enough?

Your code sets the string of the buttons to 'i'. Your comment means, that you want to get the BackgroundColor. Both are different problems.

It doesn't work because handles.pushbutton(i) does not evaluate to handles.pushbutton1 (when i is one). To work around this with GUDIE you would either need to use dynamic field names (recommended) or eval
e.g.:
set(handles.(sprintf('pushbutton%d',1)),'String',num2str(i))
or
set(eval(eval('sprintf(''handles.pushbutton%d'',1)')),'String','i')
which is highly recommended against.

This will get the background color of all buttons as a cell:
state.allpushbuttonBG = get([handles.pushbutton],'Backgroundcolor');
and to set it later:
set([handles.pushbutton], 'Backgroundcolor', state.allpushbuttonBG);
I cannot try it currently, perhaps you need addition curly braces:
set([handles.pushbutton], {'Backgroundcolor'}, state.allpushbuttonBG);

[handles.pushbutton] --> sadly, Matlab cannot understand handle of all pushbuttons in the figure by this command...
