Abstract :
In this paper we present a FORTRAN program which solves the initial-value problem associated with nonstiff system of the form y″ = ƒ(x,y). The program is based on a family of exponential-fitted four-step methods. The presented code is particularly suited to solve second-order initial-value problems arising from physics.
