Short description:

The code is an automatic continuation solver based on the code colnew.f which approximates  the solution of the differential equation by a piecewise polynomial with collocation at Gauss points. The  release of the code available here is not equal to the original code, but has been changed in order to work in R. This explain why we have added R at the end of the name.


How to perform tests:

The file report.f contains a user interface.

Once you have obtained all the fortran files,  in the directory tests you can run 

make PROBLEM=problem SOLVER=colmodR

where problem is one of the problem of this testset. This will yield the executable "dotest" that solves the problem, of which the Fortran routines are in the file problem.f.
