Condition numbers for linear systems and Kronecker product linear systems with multiple right-hand sides
Haiming Zhang, Hua Xiang, Yimin Wei · International Journal of Computer Mathematics · 2007
In this paper we investigate linear systems with multiple right-handed sides in the form of AX=B and (A ⊗ B)X=C. We derive normwise, mixed and componentwise condition numbers for these linear systems. Examples are given to evaluate the tightness of the first-order perturbation bounds.
