In this paper, we present an improved method for solving Riccati equations, which possesses a fast convergence rate and high accuracy. This modification is based on a previous approach used for solving Riccati equations (Tang and Li in Appl Math Comput 194:431–440, 2007). The Riccati equation is first transformed to a second-order linear ordinary(More)
