% Create a figure with two subplots and return the two axes objects, |ax1|
% and |ax2|. Plot random data in each subplot. Add a legend to the upper
% subplot by specifying |ax1| as the first input argument to |legend|.

y1 = rand(3);
ax1 = subplot(2,1,1); 
plot(y1)

y2 = rand(5);
ax2 = subplot(2,1,2); 
plot(y2)

legend(ax1,'Line 1','Line 2','Line 3')
