General linear methods (GLMs) are a large family of methods which have been already introduced for the numerical solution of Volterra integral equations of the second kind. In this paper, various issues relevant to the implementation of these methods in a variable stepsize environment are discussed, and the corresponding code is developed.

Volterra积分方程的一般线性方法的实现

通用线性方法（GLM）是一大类方法，已经为第二类Volterra积分方程的数值解引入。在本文中，讨论了与在可变步长环境中实现这些方法有关的各种问题，并开发了相应的代码。
