A n · n real matrix P is said to be a real generalized reflection matrix if P = P and P = I. A n · n real matrix X is said to be a reflexive matrix with respect to the generalized reflection matrix P… (More)

An efficient method based on the quotient singular value decomposition (QSVD) is used to solve the constrained least squares problem min ‖T − BXAT ‖F over symmetric, skewsymmetric, and positive… (More)

We say that $X=[x_{ij}]_{i,j=1}^n$ is symmetric centrosymmetric if x ij = x ji and x n − j + 1,n − i + 1, 1 ≤ i,j ≤ n. In this paper we present an efficient algorithm for minimizing ||AXA T − B||… (More)

Measured and analytical data are unlikely to be equal due to m easured noise, model inadequacies and structural damage, etc. It is necessary to update the physic al parameters of analytical models… (More)
