Thank yuu.If two centroids are 5 elements apart, I think it is "too close",then I choose the bigger value.Which function should I use to tell Matlab to do this?

Well, the "if" function comes to mind
if distanceApart < minAllowableDistanceApart
% Code to throw away one of the two centroid locations
end

Thank you for your kindness and patience.
But I can not program it .
Would you like to write some matlab code ?
Sorry if I take your time.

Yes you can. I have confidence in you. Once you read the "Getting
started" documentation, watch a few of the MATLAB video tutorials, and
do some of the other self-learning opportunities they provide, you'll
be programming miracles just like the hundreds of thousands of the
rest of us. It just seems hard at first. Just dedicate some time to
learning the basics and you'll be on your way. Even if I wrote that
little script for you, you can't really do much with it. You'd then
be wanting more and more MATLAB code, since I'm sure this is not the
final extent of what you'll need in MATLAB. Please recall the old
Chinese man/fish proverb.

Thank you!I will make it by myself.
Thank you for your kindness and patience.
