Hi,
I have many clusters of zeros surrounded by ones in my binary matrix. How can I find the position of the clusters of zeros without returning positions of every single zero in the cluster. I just need the position of one zero within each of the clusters.
Thanks for your help.

did you search for cluster in the file exchange?

Yes, but I am hoping to find something that is much simpler. The examples I found in file exchange were more complicated than I need. Basically, I have groups of 0s in my matrix that I want to find the position of and I am hoping there is an easy to follow way of doing so.

eg
A = [...
1 1 1 1 1 1 1 1 1 1
1 0 0 1 1 1 0 0 1 1
1 0 0 0 1 1 1 0 0 1
1 1 0 1 1 1 1 0 0 1
1 1 1 1 1 1 1 0 0 0
1 1 1 1 0 0 1 1 1 1
1 0 1 1 0 0 1 1 1 1
1 0 1 0 0 1 1 1 0 1
1 1 1 0 0 1 0 1 0 1
1 1 1 1 1 1 1 1 1 1];
STATS = regionprops(~A, 'Centroid' , 'PixelList' )
