Hi,
I'd like to let edu-sig know about this project I've been working on.
It is too under-documented to be really useful as an educational tool ATM,
but a lot of the concepts behind the code are both simple to understand and
deeply profound, mathematically.
Hence this post to edu-sig.
Check it out!
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.
