Thanks for the context. It often helps.
Here is a suggestion:

clf
subplot(1,2,2)
ax1  =  gca();
x  =  linspace(-2,7,100);
plot(x,  sin)

axt  =  newaxes();
axt.axes_bounds  =  ax1.axes_bounds;
plotframe([0  0  1  1]);
set(axt,  "box",  "off",  "margins",[0  0  0  0],"axes_visible","off","filled","off")
title("My title in normalized coodinates",  "position",[0.2  0.9],"fontsize",4)

sca(ax1);


Here, it's possible to control the normalization reference. This example 
uses
the entry area as the reference area. So it can be a subarea, not the 
whole figure.
But you can set it to the whole figure (or uicontrol frame) if you think 
it more handy.
