Perturbation for the Generalized Bott-Duffin Inverse
Guo Liu · Journal of Eastchina Normal University · 2000
A Perturbation theory for the generaiized Bott-Duffin inverse A (+) (L) of A with respect to a subspace L is developed. Meanwhile this paper defines the generalized Bott-Duffin condition number K gBD (A)=‖A‖·A (+) (L) .
