评论： Vivek 2014-4-9

I created two radiobuttons on panel in GUI through script.I can select both at the same time (ie) selection is not removed when another radio bttn is selected.

Even I checked the parent of both radio button. It is same.

f1=get(findall(0,'Tag','English0'),'Parent')

f2=get(findall(0,'Tag','Metric1'),'Parent')

f1 and f2 both are same Then why a normal radio buttons functionality in single panel is not achieved?

Please suggest ideas.

Panels are basically just cosmetic. Use a uibuttongroup to manage the exclusivity behavior you want. Compare:

figure
pnl = uipanel('position',[0.1 0.1 0.5 0.5]);
b1 = uicontrol('parent',pnl,'units','normalized','position',[0.1 0.1 0.8 0.4],...
    'style','radiobutton','string','I am a choice');
b2 = uicontrol('parent',pnl,'units','normalized','position',[0.1 0.5 0.8 0.4],...
    'style','radiobutton','string','I am a choice');

versus

figure
pnl = uibuttongroup('position',[0.1 0.1 0.5 0.5]);
b1 = uicontrol('parent',pnl,'units','normalized','position',[0.1 0.1 0.8 0.4],...
    'style','radiobutton','string','I am a choice');
b2 = uicontrol('parent',pnl,'units','normalized','position',[0.1 0.5 0.8 0.4],...
    'style','radiobutton','string','I am a choice');

You don't have to specify parents to most graphical objects, but it's a recommended practice because it ensures that things end up where you expect them to. In this case, you really want the radio buttons to be inside the button group, because that manages the exclusivity.
