Subject: Reconstruct determinant of the Hessian

Hi all,

in quasi Newton methods in optimization the Hessian of the target function is reconstructed.
This means  that one needs to store a  matrix in each step.
If one needs only the *determinant* of the Hessian, is
there a trick to get it without storing the whole matrix?

Thanks

Karl
