摘要：
This paper considers the problem of perturbation analysis for the QR factorization of a special architecture called unitary-symmetric matrix. The perturbation bounds of the triangular factor and orthogonal factor in the QR factorization of unitary-symmetric matrix are derived, together with the perturbation bound correspondences between the unitary-symmetric matrix and its mother matrix highlighted.
