Level-2 condition numbers for least-squares solution of Kronecker product linear systems
Wenhua Kang, Hua Xiang · International Journal of Computer Mathematics · 2008
Kronecker product linear systems arise more and more often in the real world. In this paper, we consider the minimum norm least-squares solution of Kronecker product linear systems (A⊗ B)x=b by extending some known results from nonsingular cases to singular or rectangular cases. We investigate the level-2 condition numbers, and the corresponding bounds of these condition numbers.
