how can i translate the overlapping polygos to new location so that there is no overlap.
A=[];
N = 20;
for i=1:N
X = randn(N,2);
R = sqrt(rand(N,1));
X = R .* X ./ sqrt(sum(X.^2,2));
X=.05.*X;
XX=X(:,1);
XY=X(:,2);
XX=XX+rand;
XY=XY+rand;
K=convhull(XX,XY);
polyin=polyshape(XX(K),XY(K));
polyarray=regions(polyin);
AB=[XX(K),XY(K)];
A=[A; AB];
plot(XX(K),XY(K));
hold on
end

c(i)=polyin;
AB=[XX(K),XY(K)];
A{i} = AB;
TF = overlaps(c);
end
[R, C] = find(TF);
A(R(~(R==C))) = [];
for i = A
plot(i{:}(:,1), i{:}(:,2))
hold on;
end

Use area and intersect (possibly with polybuffer) as shown in this post on Loren Shure's blog to identify overlapping polygons. Alternately if you're using release R2018a, use the overlaps function introduced in that release. [The blog post was written before R2018a was released and so couldn't use overlaps.]
When you've identified polygons that overlap, translate the corresponding polyshape or polyshapes to move it or them to a different location then retest for overlaps.

yes but i have deleted the overlapping one ..coz translating them can take very very long ..coz if the numbers of polygons are more .translation will be never ending loop .
