本文介绍了一种用于隐式微分方程组/代数方程组数值求解的新程序DASSL。这些方程被写成F(t，y，y‘)=0的形式，并且它们可以包括比标准形式的ODE系统y’=f(t，y)复杂得多的系统。微分/代数方程在物理世界中有几种不同的应用。我们概述了DASSL中使用的算法和策略，并解释了代码的一些功能。此外，我们还简要介绍了使用DASSL解决问题需要做些什么。
This paper describes a new code DASSL, for the numerical solution of implicit systems of differential/algebraic equations. These equations are written in the form F(t,y,y') = 0, and they can include systems which are substantially more complex than standard form ODE systems y' = f(t,y). Differential/algebraic equations occur in several diverse applications in the physical world. We outline the algorithms and strategies used in DASSL, and explain some of the features of the code. In addition, we outline briefly what needs to be done to solve a problem using DASSL.
