Rigorous Perturbation Bounds for the QX Decomposition for Centrosymmetric Matrices

Aamir Farooq, Rewayat Khan, Uzma Rani +1

Konrad Burnik suggests a structure-preserving QR factorization for centrosymmetric matrices, known as QX factorization. In this article, we obtain the explicit expressions for rigo…
