Use a loop and uncheck/check them.

%create 20 checkboxes
for i=20:-1:1
    handles.uihandles(i)=uicontrol('style','checkbox','position',[100 600-i*25 20 20]);
end
set(gcf, 'Position', get(0, 'Screensize'));
%create 1 pushbutton
uicontrol('style','pushbutton','string','check all','position',[200 600 80 40],'callback',{@check_all_callback,handles});

function check_all_callback(~,~,handles)
if handles.uihandles(1).Value==1 %if the last checkbox is checked, uncheck all
    for i=1:20
    handles.uihandles(i).Value=0;
    end
else
    for i=1:20                    
    handles.uihandles(i).Value=1; %if the last checkbox is unchecked, check them all
    end
end
end

If you are using guide/appdesigner your handles will not be indexed as in my example. In that case use sprintf to construct handle names.
