How can I divide/merge my subplots?

Hi! I want to plot this figure -

As you can see, the first plot is taking the 3 columns. And the last 6 plots are taking one columns only. Can anyone please tell me how can I write down tha code to plot this figure?

subplot(3, 3, 1:3);
plot(rand(1, 10), '.-');
subplot(3, 3, 4);
plot(rand(1, 10), '.-');
subplot(3, 3, 5);
plot(rand(1, 10), '.-');
subplot(3, 3, 6);
plot(rand(1, 10), '.-');
subplot(3, 3, 7);
plot(rand(1, 10), '.-');
subplot(3, 3, 8);
plot(rand(1, 10), '.-');
subplot(3, 3, 9);
plot(rand(1, 10), '.-');
