# DEPAC - design of a user oriented package of ODE solvers

## Abstract

DEPAC is a user interface to a package of codes for the solution of the initial value problem for a system of ordinary differential equations. It is intended to make the codes in the package as easy as possible to use and, at the same time, to take full advantage of the underlying algorithms. A major objective of the design is to facilitate switching codes. The prologs for the three methods at present represented in DEPAC are given. This document discusses some aspects of the design of DEPAC. It explains why the design is appropriate to the authors' computing environment. It provides ideas, experience, and a discussion of issues which will assist researchers faced with a similar task in other environments.
