A = [0,0; 5,10; 10,15; 85,90; 95,95];
pairs = cell(size(A,2),1);
for K = 1 : size(A,2)
pairs{K} = [A(1:end-1,K), A(2:end,K)];
end

A = [0,0; 5,10; 10,15; 85,90; 95,95];
pairs = zeros(size(A,1)-1, 2, size(A,2));
for K = 1 : size(A,2)
pairs(:,:,K) = [A(1:end-1,K), A(2:end,K)];
end
Now pairs(:,:,K) corresponds to the K'th column of the original array.
