Yes it is

Yes, subplot() is not dedicated to this task. There are several ways
to do what you whish. One of the easiest and most straightforward one
is to fit the .axes_bounds property by hand. Here is the most simple
example i may propose to you:

plot() // plots a sample with 2 subplots
a=gca(); // gets the handle of the last plot
twinkle(a) // to see which one was the last plotted
a.axes_bounds=[0 0.41 1 0.55 ];

You can even share a common X axis within different plots, etc.

To know more about possibilities, see as a starting point: help 
axes_properties
and display the handle:
a  <return>
