Left and right inverse eigenpairs problem of generalized centrosymmetric matrices and its optimal approximation problem
Earlier the authors [Appl. Math. Comput. 177, 105--110 (2006; Zbl 1098.65039)] obtained some results for a certain inverse eigenproblem, and an associated approximation problem, for skew-centrosymmetric matrices. This paper gives similar results for the corresponding problem for matrices \(A\) satisfying \(A=KAK\), where \(K\) is a given permutation matrix. For some related results, see the authors [Math. Numer. Sin. 29, No.~4, 337--344 (2007; Zbl 1143.65334)].
