matlab - Plotting subplots from figures -

i iteratively create subplots figure. have following code:

for i=1:numel(snips_timesteps)         x=openfig(sprintf('./results/snips/temp/%d.fig',i),'reuse');         title(sprintf('timestep %d',snips_timesteps(i)));         xlabel('');         ax= gca;         handles{i} = get(ax,'children');         close gcf;     end     h3 = figure; %create new figure     i=1:numel(snips_timesteps)         s=subplot(4,4,i)         copyobj(handles{i},s);     end 

error is:

error using copyobj copyobj cannot create copy of invalid handle.    k>> handles{i}  ans =    3x1 graphics array:    graphics    (deleted handle)   graphics    (deleted handle)   graphics    (deleted handle) 

is possible close figure still retain it's handle? seems reference being deleted.

edit

    handles={};     i=1:numel(snips_timesteps)         x=openfig(sprintf('./results/snips/temp/%d.fig',i),'reuse');         title(sprintf('timestep %d',snips_timesteps(i)));         xlabel('');         ax= gca;         handles{i} = get(ax,'children');         %close gcf;     end     h3 = figure; %create new figure     i=1:numel(snips_timesteps)         figure(h3);         s=subplot(4,4,i)         copyobj(handles{i},s);         close(handles{i});     end 

error:

k>> handles{i}  ans =     3x1 graphics array:    line   quiver   line  k>> close(handles{i}) error using close (line 116) invalid figure handle. 

if remove close(handles{i}) plots first figure again subplots!

no. closing figure deleting , of data associated including handle.

if remove close gcf; , place figure(i); close gcf; after copyobj(handles{i},s); desired affect. however, need add figure(h3); before s=subplot(4,4,i) ensure subplot added correct figure.

here sample code show working. first creates 4 figures , grabs handles axes it. loop on each figure , copy subplot of figure.

for = 1:4     figure(i)     y = randi(10, [4 3]);     bar(y)      ax = gca;     handles{i} = get(ax, 'children'); end  = 1:4     figure(5);     s = subplot(2, 2, i);     copyobj(handles{i}, s);     figure(i);     close gcf; end
