How can I use imfindcircles in real time video?

I have written below code which gives photo from camera and mark circles on them
vid = videoinput('winvideo', 1, 'RGB24_640x480');
set(vid, 'FramesPerTrigger', Inf);
set(vid, 'ReturnedColorspace', 'rgb')
vid.FrameGrabInterval = 5;
data = getsnapshot(vid);
[center,radii] = imfindcircles(data,[20 60],'ObjectPolarity','dark','Sensitivity',0.9,'Method','twostage');
imshow(data)
h=viscircles(center,radii);
how can I make this working in real time?

You may not be able to. How long does it take to call imfindcircles()? Wrap it in tic and toc to find out. It may take longer than 1/30th of a second or whatever your definition of "real time" is.

Well it was just a suggestion. You're free to work on a faster method. And no, I don't have one ready to hand over to you, or even know of one. Plus I don't use Simulink.

Two ways to get IMFINDCIRCLES run faster in your code are:
1) Sending in the image at a lower resolution.
2) Use smaller radius range, if possible.
