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, C christiansen and russell

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 Using Continuation, As Descri

双精度COLSYS子程序，用于求解常微分线性、非线性方程组。经过扩容后版本可以求解1000个最高阶次为4阶的方程组。并达到令人满意的精度。-Double precision COLSYS subroutine, used to solve ordinary differential linear, nonlinear equations. After expansion version can solve the 1000 highest order for 4 order equation.

单精度COLSYS子程序，用于求解常微分线性、非线性方程组。经过扩容后版本，可以求解1000个最高阶次为4阶的方程。-Single precision COLSYS subroutine for solving ordinary differential linear, non-linear equations. Expansion or later, you can solve the 1000 highest order for the fourth-order equation.
