Abstract
The numerical solution of discrete-time algebraic Riccati equations is discussed. We propose to compute an approximate solution of the discrete-time algebraic Riccati equation by the (butterfly) SZ algorithm. This solution is then refined by a defect correction method based on Newton´s method. The resulting method is very efficient and produces highly accurate results
