Details:

Matlab and Octave produce the same results for


clf
imagesc (1./hilb(4))
hold on
plot (1:4, 's-')
 

But if the order if switched ...


clf
plot (1:4, 's-')
hold on
imagesc (1./hilb(4))
set (gca, 'children', flipud (get (gca, 'children')))
 

... Matlab correctly respects the existing axis limits and y-axis
orientation, while Octave does not. For reference, see the hold_2_1.png plots
at the link below.
