change the font size of the current axis

How can I change the font size of the axis of the current graph without creating new axis? For example, if we have this plot already, how can I change the font size?

x = rand(10,10);
y = rand(10,10);
plot(x,y)

x = rand(10,10);
y = rand(10,10);
plot(x,y);
set(gca,'FontSize',20)
