Re: [Yanl-develop] Contribution

[Constantine A. <aco...@us...>]

Karsten,

I wrote the example harmonic oscillator which is attached.

I'm having trouble evaluating the results, because the structure of
the library is rapidly changing when I do an svn update. The library
also seems somewhat complicated to use to me.

Each of the boost libraries has a web-based introduction to the
library on the boost website. Most of them do a good job of telling
the story of how the library is used, and why it evolved the way it
did. I find the pages for Concept Check especially exemplary of this.
Does odeint have anything similar? That might make it easier for
newcomers to understand the changes that are taking place, and the
design decisions that have been made.
