i am capturing images from a camera in real time and displaying the processed image in a while loop. As soon as I close the figure window, an error pops up. I want to execute stop(vid) after i close the figure and don't want the error to exist.
the error is as given below
Error using matlab.ui.Figure/set Invalid or deleted object.
Error in imshow (line 343) set(fig_handle, 'NextPlot', 'replacechildren')
Error in LiveDetector (line 40) imshow(imgOut);toc;

use the close request callback that I linked to . That is exactly the kind of purpose the callback was designed for.

use a callback to detect the close attempt .use it to stop the video before deleting the figure.
