The iterative algorithm for solving a class of generalized coupled Sylvester-transpose equations over centrosymmetric or anti-centrosymmetric matrix

In this paper, an iterative algorithm is presented for solving a class of generalized coupled Sylvester-transpose linear matrix equations over centrosymmetric or anti-centrosymmetric matrix. If the matrix equations are consistent, the solution through the iterative method can be obtained within finite steps without round-off error for any initial centrosymmentirc or anti-centrosymmetric value. Furthermore, one method is provided by choosing the special initial matrices to obtain the least norm solution. Finally, numerical examples are presented to demonstrate the efficiency of the algorithm we have proposed.
