I can see no objections against Matlab compatibility. Matlab supports figure
handles aswell as axes handles. Command subplot in Matlab accepts vector as
the third argument in the same manner as Octave does. Also plot function
accepts axes handle as the first argument. Therefore the following syntax
should work. Have you tried it?

fig = figure;
ax(1) = subplot(4,2,1);
ax(2) = subplot(4,2,3);
ax(3) = subplot(4,2,[2,4]);
ax(4) = subplot(4,2,[5,7]);
ax(5) = subplot(4,2,[6,8]);

bode(sys,ax);
---
function bode(sys,ax)
  ...
  plot(ax(1),x1,y1);
  plot(ax(2),x2,y2);
end
