Circle buffer for images from webcam

Hi

Please tell me how to organize a circular buffer of images from the camera.

This is my code that allows to shoot a image stream. And I want to write them to a circular buffer for later processing

clear all;
devs = webcamlist;
cam = webcam(devs{1});
 
global LOOP_RUNNING;
LOOP_RUNNING = true;
img_display = figure('CloseRequestFcn',@my_closereq);
while (LOOP_RUNNING)
 
  img = snapshot(cam);
  subplot(2,2,1),imshow(img);
  pause(0.05);
end
 
function my_closereq(~,~)
  global LOOP_RUNNING;
  LOOP_RUNNING = false;
  delete(gcf);
  clear('cam');
  return; 
end

You can refer to the Insert elements into a 4D array MATLAB Answer which might help you to get started on your implementation. The following resource might also help: circular buffer.
