Where M0 is the set of all points.
CODE:
dc=centroids(:,2);
idx2=MO(:,1)>=-50;
idx3=MO(:,1)<=100;
idx4=MO(:,2)>=dc;
dataC=MO(idx2,:);
dataD=MO(idx3,:);
dataE=MO(idx4,:);
dataF=intersect(dataC,dataD,'rows');%Finding the intersection of dataF,
dataG=intersect(dataF,dataE,'rows');%Finding the intersection of dataG

Here is your data looks like
s = load('M0.mat');
[x,y] = deal(s.M(:,1),s.M(:,2));
plot(x,y)
