Various Scientific Software

The different ports of various algorithm or applications is just a few that I have come across and that I believe would be of interest for this web sites visitors.

Newton's method by Madsen C++
Probably the most instructive and efficient implementation of Newton method for finding all roots of polynomials with real coefficients. This is a C++ port of Madsen algorithm from Bit 13 (1973) pp 71-75.

Jenkins-Traub C++
The famous Jenkins-Traub algorithm for finding all roots of polynomials. This is a C++ version for complex coefficients.  A real coefficients version can be found on www.crbond.com.

Renormalized Graeffe Iteration by Malajovich
The new 'reborn' Graeffe iteration for finding roots of univariate polynomials (See Malajovich paper On The Geometry of Graeffe Iteration, together with Jorge P. Zubelli) . It is distributed under GNU Public License Agreement version 2.

http://www.dma.im.ufrj.br/~gregorio/software.php
This is a C (Linux) version for complex coefficients as a standalone C program.
