摘要
In this paper, an explicit Runge-Kutta-Nystrom method is designed for the numerical integration of stiff oscillatory problems with two frequencies. The new method is of algebraic order five. Numerical experiments are carried out to illustrate the efficiency and robustness of our new method in comparison with some well-known methods in the recent literature. © 2013 ISSN 1881-803X.
