I hope this helps. If not, please rectify. S is your vector. A is a 6964*6964 matrix which returns the difference between other elements of the vector on corresponding columns
A=zeros(length(S));
for i=1:length(S)
for n=(i+1):length(S)
A(n,i)=S(i)-S(n);
end
end

bsxfun(@minus, matrix(:), matrix(:).') % for newer versions bsxfun() is not needed
