How to add a title for any subplot in addition to a subplot title?

Let's assume I want to plot a few series using subplot:

x = randn(20,12);

for i = 1:size(x,2)
    subplot(3,4,i)
    plot(x(:,i),'-k')
    title('Title')
end

Now, I want to add a title for each of the three rows. I only manage to display one for the first row as follows:

sgtitle('Title row I')

for i = 1:size(x,2)
    subplot(3,4,i)
    plot(x(:,i),'-k')
    title('Title')
end

How can I add an "sgtitle" for every new row?

Thanks!

You can do this sort of thing with tiledlayout instead of subplot, taking advantage of nested layouts:

t = tiledlayout(3,1);  % tiledlayout to hold other tiledlayouts
for i = 1:3
    tt = tiledlayout(t,1,4);
    tt.Layout.Tile=i;
    for ii = 1:4
        nexttile(tt)
        plot(rand(10,1))
        title('axes title')
    end
    title(tt,sprintf('Row %d Title', i),'FontSize',11)
end
title(t,'Master Title')
