This seems very well suited to be an extension to `diffgeom`. There is a __lot__ that can be done to extend this module. Most of what you describe is already implemented in some manner (not necessarily well), but just extending it and fine tuning it could be enough for a project. > One more question can this be > implemented as a project during summer. I guess you mean a GSoC project. I would guess it is appropriate. It all depends on the details in your application. On the other hand, if you want to do it outside of GSoC, we would be happy to help you along the way. -- You received this message because you are subscribed to the Google Groups "sympy" group.
