This is it, exactly.

Now, I just need to extract the polygon from A(:,[10,11]))

octave5 > n=size(A,1);
octave:6> idx=A(1:n-1,[10,11]) != A(2:n,[10,11]);
octave:7> P1=A(2:n,[10,11]);
octave:8> P1=P1(idx(:,1) != idx(:,2),:)
ans =

     0   100
  -100   100
  -100     0
     0     0
  -100     0
  -100   100
     0   100
     0     0

Thanks.
