How do I make a set of mutually exclusive radion buttons?

Hi all.

I am trying to make a GUI which essentially generates the ksdensity plot of the selected radiobutton from a list of displayed radiobuttons. But, when I select one of the radiobuttons, the previously selected does not get unselected. My code for generating the radiobuttons:

f      = figure;
 posFig = get(f,'Position');
 hFig   = posFig(4);   % height of the figure

 fields = fieldnames(ranked_rbc); %ranked_rbc is a structure variable
 for k=1:1:6
    rdbutton(k) = uicontrol('Style','radiobutton','String',fields{k},            ...%fields is a cell array that generates the radiobutton titles
                          'Value',0,'Position',[20 hFig - (20*(k-1)+50) 130 20], ...
                          'Callback',{@radioButtonCallback,k});
 end

My code for the callback function:

function radioButtonCallback(source, data, index)
    fprintf('Radion Button %s is %d\n',get(source,'String'),get(source,'Value'));
    rbc_plot=load('training_rbc.mat');
    infected_plot=load('training_infected.mat');
    rbc_plot = rbc_plot.rbc_Selected;
    infected_plot = infected_plot.infected_Selected;
    fields = fieldnames(rbc_plot);
    plot_ksdensity(double(rbc_plot.(get(source,'String'))));
    hold on;
    plot_ksdensity(double(infected_plot.(get(source,'String'))),'r');
    xlabel(get(source,'String'));
        ystr = strcat('probability density of',get(source,'String'));
        ylabel(ystr);
        legend('RBC Cells','Infected Cells');
        hold off;
 end

How do I make the radiobuttons mutually exclusive and where do I need to add the code for that? Thanks for the help.
