How do I copy a figure object and its descendants to another object of the same class in MATLAB?

I have a figure with several objects such as curves, annotations etc. I want to be able to copy all the objects in the figure to another figure while retaining the same hierarchy.

The function COMPCOPY below is an example of how to implement such a functionality.

function compCopy(op, np)

%COMPCOPY copies a figure object represented by "op" and its % descendants to another figure "np" preserving the same hierarchy.

     ch = get(op, 'children');

     if ~isempty(ch)   

         nh = copyobj(ch,np);

         for k = 1:length(ch)

             compCopy(ch(k),nh(k));

         end

     end;

   return;

The function can be used as follows

hf1 = figure;

ax1 = subplot(211);

plot(1:10);

title('First Figure');

ax2 = subplot(212);

plot(31:40);

title('Second Figure');

hf2 = figure;

compcopy(hf1, hf2);

For information on the COPYOBJ function execute the following at the MATLAB command prompt:
