Numerical Integration by a Method of Interlocked Parabolas by Thomas S.Walton

摘要

Simple, yet reasonably accurate, numerical methods for solving differential equations are frequently required in many branches of engineering science. To help satisfy this need a general method for integrating systems of first-order differential equations has been developed. Two integration formulas are given. One of these is used to correct the solution up to the end of the current step, and the other is used to predict the solution one step ahead.
