An Iterative Algorithm for the Least Squares Centrosymmetric Solution of a Matrix Equation

In this paper, the linear mapping from the constrained solution sets to their independent parameter spaces is constructed, and its properties are studied. Based on these properties and the classical algorithm LSQR for solving the (unconstrained) LS problem, a matrix iterative method that can find the special Centro symmetric solution is proposed. Numerical results are reported that show the efficiency of the proposed method.
