How can I create a Figure Title with a variable in it?

I have a figure:

DEPTH = 10; % Depth changes based on user input
figure('Numbers at a depth of %d meters)')

How can I make my figure title update depending on my input for depth?

[Adam Danz]

DEPTH = 10; % Depth changes based on user input
title(sprintf('Numbers at a depth of %.0f meters', DEPTH))

% For the figure name (not title):
figure('Name', sprintf('Numbers at a depth of %.0f meters', DEPTH)) 

I prefer %.0f rather than %d to convert integers because 1) if DEPTH isn't an integer, %d will print out scientific notation and 2) if you ever want to add decimal places you can just change the 0.

However keep in mind that %f has a limited precision, whereas %d does not. See:
