摘要:

AbstractOne‐step integration methods of fourth‐order accuracy using an odd number of function evaluationsK, to solvedy/dt= A ·y, are proposed. These methods have an imaginary stability limit\documentclass{article}\pagestyle{empty}\begin{document}$ S_{1\;} = \sqrt {(K - 1)^2 - 4} $\end{document}. In the caseK= 5 the Kutta‐Merson method r
