Apologies if this is too off-topic for these lists, but
I hope some people here find this interesting!
PyDX - first public announcement
PyDX is a package for working with calculus (differential geometry),
arbitrary precision arithmetic (using gmpy), and interval arithmetic.
* multivariate automatic differentiation (to arbitrary order)
* Tensor objects for computations in differential geometry
* Interval scalars (based on libMPFI) for calculating rigorous bounds
on arithmetic operations (validated numerics).
* Arbitrary order validated ODE solver.
PyDX uses lazy computation techniques to greatly enhance performance of
the resulting functions.
This code grew out of a research project at The Australian National University,
Department of Physics, which involved computing bounds on geodesics in
