>From matlab on-line document, axes 'position' property provides the
specifications of the plot area, i.e., [x0 y0 width height].  See "Control
Axes Layout".  

The following example shows Octave axes position, same definition, may not
update when plot area is changed.  The example shows that the two figures are
the same in dimension but with two different plot areas.  But [x0 y0] are
identical which is not what I had expected.   x0 must be different viewing the
displayed figures/axes, see attached zip files.  

Any user's calculation based on [x0 y0] would be invalid.  

Thanks.  

figure; 
h=plot([0 1], [0 1]); display(get(gca, 'position'));  
hgsave('rectangle.ofig')
axis square; drawnow;  display(get(gca, 'position')); 
hgsave('square.ofig')

>> figure;
>> h=plot([0 1], [0 1]); display(get(gca, 'position'));
   0.1300   0.1100   0.7750   0.8150
>> hgsave('rectangle.ofig')
>> axis square; drawnow;  display(get(gca, 'position'));
   0.1300   0.1100   0.7750   0.8150
>> hgsave('square.ofig')
