Add a title to a group of 4 subplots centred at the top

I have a group of subplots and want to add a title at the top, centre. How might one do this? Here is an MWE

subplot(2,2,1)
plot(peaks)

subplot(2,2,2)
plot(peaks)

subplot(2,2,3)
plot(peaks)

subplot(2,2,4)
plot(peaks)

Answer 1

I would suggest using tiledlayout instead of subplot. Then you attach the title to the tiledlayout rather than any of the individual plots.

tl = tiledlayout(2,2);
nexttile
plot(peaks)
nexttile
plot(peaks)
nexttile
plot(peaks)
nexttile
plot(peaks)
title(tl, 'Common title')

Use the sgtitle function (introduced in R2018b).

It works with subplot and tiledlayout figures.
