title: Improvements in the discrete-dipole approximation method of computing scattering and absorption.
abstract: Improvements in complex-conjugate gradient algorithms applied to the discrete-dipole approximation are reported. It is shown that computational time is reduced by use of the stabilized version of the biconjugate gratings algorithm, with diagonal left preconditioning.
