The ButtonGroup controls require the GUI Layout Toolbox by Ben Tordoff and David
Sampson available at:

The controls in this submissionshould be placed in the +uiextras folder in the GUI Layout Toolbox or in another folder called +uiextras that resides under a folder on your path. It is recommended to run rehash path after doing this.

EXample:
function buttonGroupExample
f = figure;
vb = uiextras.VBox('Parent',f,'Units','Normalized');
bgH = uiextras.HButtonGroup('Parent',vb,'Buttons',{'1','2','3'},'Spacing',50,'Padding',10,'SelectedChild',1,'SelectionChangeFcn',@onSelectionChange);
hb = uiextras.HBox('Parent',vb);
bgV = uiextras.VButtonGroup('Parent',hb,'ButtonStyle','toggle','Buttons',('123')','Spacing',20,'Padding',10,'SelectedChild',3,'SelectionChangeFcn',@onSelectionChange);
p = uiextras.Panel('Parent',hb);
set(hb,'Sizes',[100,-1]);
lblDisplay = uicontrol('Parent',p,'FontSize',16,'Style','text');
onSelectionChange([],[]);
function onSelectionChange(src,evt)
disp(evt);
set(lblDisplay,'String',int2str([bgH.SelectedChild,bgV.SelectedChild]));
end %onSelectionChange
end %buttonGroupExample
