Abstract:
An algorithm was constructed to solve the least squares bisymmetric solution of a class of matrix equation. Some properties of the iterative sequence have been derived, and the method has been shown to preserve convergence properties. Numerical examples show that the iterative method is efficient.[著者文摘]
