Abstract:
In this paper, an iterative algorithm is proposed to find the generalized centrosymmetric
solution pair [X, Y ] of matrix equation AXA~T+BYB~T=C. The solvability of the matrix equation can be determined automatically in the iterative process. When the matrix equation is consistent, the solution pair can be obtained within finite steps in the absence of round-off errors. Meanwhile,the optimal approximation solution for given matrix pair [X*, Y*] can be derived by this method. Finally,the numerical examples given illustrate the efficiency of the iterative algorithm.
