I have two graphs generated by a code and now I want to use the code blow to plot them on a 2x1 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

在 MATLAB Online 中打开

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)

This following function helps you to put several fig files next to each other as subplots: http://www.mathworks.com/matlabcentral/fileexchange/51236-subplot It is important to note that all the saved fig file should be 2D and single plot (No subplots)
