Abstract
It has recently been observed that the symmetric case of the biconjuga te gradient method renders a variational formula for the monostatic sc attering amplitude stationary in the available Krylov subspace at each iteration. In this Letter I point out that the general biconjugate gr adient method makes stationary the analogous variational formula for a bistatic scattering amplitude and suggest likely practical benefits a ccruing from this property.
