rrspace: Effective computations of Riemann-Roch spaces on curves defined over Z/pZ.

rrspace is a software for computing efficiently Riemann-Roch spaces on nodal plane curves, based on the work done by Aude Le Gluher during her Master's thesis. It also implements arithmetic on Jacobians of nodal curves. It is distributed under the LGPLv2.1+ license.

NewtonSLRA: Maple library for numerical Structured Low-Rank Approximation.

Library: NewtonSLRA.tar.gz
Maple source code: NewtonSLRA.mpl approxGCD.mpl matrixCompletion.mpl
Installation, documentation and examples.

This Maple library implements the algorithm NewtonSLRA from the paper A Quadratically Convergent Algorithm for Structured Low-Rank Approximation (joint work with Eric Schost). It also provides routines for univariate approximate GCD and Low-Rank matrix completion based on NewtonSLRA.
