摘要
In this paper a special class of k-step methods of order k + 1 with two free parameters up to order 9 are established. The stability analysis of the P-C scheme is investigated. The coefficients of our class and the values of the parameters for getting A(0)-stable schemes are tabulated. The relation between the parameters for obtaining L(alpha)-stable formula is determined. A comparison between the stability region and the error estimation for the fourth-order of our scheme and Cash's scheme is carried on. (C) 1998 IMACS/Elsevier Science B.V.
