[Numpy-discussion] PyDX - announcement

[Simon B. <si...@ar...>]

Apologies if this is too off-topic for these lists, but
I hope some people here find this interesting!


PyDX - first public announcement
================================

Overview
--------

    PyDX is a package for working with calculus (differential geometry),
arbitrary precision arithmetic (using gmpy), and interval arithmetic.

It provides:
    * 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 
relativistic space-time's.
