Zhou Shuo, Guo Li-jie · 2003
The least-squares solutions of the inverse problem of anti-centrosymmetric matrices is discussed, and the expression of the solution is obtained. In addition, the problem of using anti-centrosymmetric matrices to construct the optimal approximation to a given matrix is discussed, the necessary and sufficient conditions about the problem are derived, and the expression of the solution is provided.
