and \(i\) yields the derivatives for all values of \(B\) and \(j\), a
whole column of the Hessian. An equivalent result is obtained for
analytic derivatives obtained from perturbation
theory~\cite{Baroni1994,Kadantsev2005}. theory~\cite{Baroni2001,Kadantsev2005}. Since we obtain the Hessian
one column at a time, only \(O(N)\) calculations are required instead
of the \(O(N^2)\) calculations required for an element by element
calculation.
