摘要
选择恰当的参数，将２￣Ｎ类算法用于代数与微分黎卡提方程。证明了算得的解是如此精确，几乎是计算机上的精确解。数例验证了该结论。
The 2￣N type algorithm is applied to both the algebraic and differential Riccati equations byselecting appropriate parameters. It is proved that the solutions are very precise,almost the exactsolutions on the computer. Numerical examples varify the conclusion.
