Running 3.0.3 you can try

x = 1:100;
y = 1./x;
Fluido = [x, 1i*y];
Masa = Fluido;

subplot (1, 2, 1)
plot (Fluido)
xlabel ('volumen')
ylabel ('presión')
title (' ')
subplot (1, 2, 2)
plot (Masa)
xlabel ('volumen')
ylabel ('presión')
title (' ')
ax = axes;
set(ax, 'visible', 'off')
title ('on the top title')

The *trick* I'm using is to add an extra axes and then to turn it  
visibility off.

In future versions you'll be able to modify the position and location  
of each axes. That will make what you want to do much easier.
