MATLAB: Keeping the same figure active

Question

If i create a figure with a certain name:

   hFig = figure('Name','ALL CAMERAS', 'Resize','on', 'Position',[600 600 400 800],'numbertitle','off');

How can I call it at different time to add subplots to it. I have tried

 figure(hFig);
 montageImg = cell2mat(allImgs);
 J = imadjust(montageImg,stretchlim(montageImg),[0 1]);
 subplot(3,2,1); 
 imshow(J);

I will vary the last digit in subplot to plot to each of the 6 positions allocated for. But currently, it just opens up a new figure called "ALL CAMERAS" for each subplot I do rather than plot all to the same figure?

Is it also possible to delete all open figures except the one called ALL CAMERAS?

Thanks

Answer 1

Your algorithm should work. The imshow should appear in the subplot you've specified. Is this really the code you're using?

As for deleting all figures but hfig:

close(setdiff(findall(0,'Type','figure'), hfig)); %or you could use findobj
