MATLAB: Plot already exisitng graphs onto one graph

plot two figures

I have two graphs generated by a code and now I want to use the code blow to plot them on a 2×1 figure. but the resulting figure, first doesn't show the graphs and second includes only one blank set of axes on top half of the page.
……………….
fig1=openfig('firstpane')
fig2=openfig('secondpane')
subplot(211)
plot(fig1)
subplot(212)
plot(fig2)
…………..
is there any easier way? I can't write a loop to generate the two figures at once because the code is quiet heavy and I'd get memory problem.
Thanks

I assume that you have two saved MATLAB figures, firstpane.fig and secondpane.fig, each with one axes object.
fh = figure;
P = subplot(2,1,1);
P1 = get(P,'pos');
delete(P)
P = subplot(2,1,2);
P2 = get(P,'pos');
delete(P)
fig1 = openfig('firstpane');
C = copyobj(gca,fh);
set(C,'pos',P1)
close(fig1)
fig1 = openfig('secondpane');
C = copyobj(gca,fh);
set(C,'pos',P2)
close(fig1)
