MATLAB: Index of box plot outliers

boxplot

I am trying to label the outliers of the box plot with year number. in the following code, pre_1 is years 1950-2010 for only january, pre_2 is the same but for Feb, and so on to Dec. I am wondering how can i get the index of each outliers, the ydata gives me the outliers value, but I still cannot find the index.
pre12345101112=[pre_1 pre_2 pre_3 pre_4 pre_5 pre_6 pre_7 pre_8 pre_9 pre_10 pre_11 pre_12];
figure;boxplot(pre12345101112)
h = findobj(gcf,'tag','Outliers');
xdata = get(h,'XData')
ydata = get(h,'YData')
thanks in advance

Try this
    m = randn(48,12);
    e = eps(max(m(:)));
    boxplot( m )
    h = flipud(findobj(gcf,'tag','Outliers')); % flip order of handles
    for jj = 1 : length( h )
        x =  get( h(jj), 'XData' );
        y =  get( h(jj), 'YData' );
        for ii = 1 : length( x )
            if not( isnan( x(ii) ) )
                ix = find( abs( m(:,jj)-y(ii) ) < e );
                text( x(ii), y(ii), sprintf( '\\leftarrowY%02d', ix ) )
            end
        end
    end
it labels the outliers
