是 COLSYS 的更新版。国外有名的解常微分BVP的求解器，对奇异问题有很好的适应性。-C this package solves boundary value problems for C ordinary differential equations, as described below. C C COLNEW is a modification of the package COLSYS by ascher,

一个解常微分边值问题的高端求解器，可以解显式表达的微分方程组，且此微分方程组的每一个方程可以容许4阶的微分。长于解非线性的奇异问题。内附论文。程序自带说明和算例。-Automatic Continuation With Collocation. This Package Solves `Stiff Boundary Value Problems For Ordinary Differential Equations By
