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.
Title of program: EXPFIT4
Catalogue Id: ADEZ_v1_0
Nature of problem
All physical problems which lend themselves to a description by a non- stiff system of linear and/or nonlinear differential equations of second order, such as pendulum problems, anharmonic oscillator problems, Lagrange problems, celestial mechanics problems, etc.
