Release 2.4.85 of PHCpack
Below are the sources and some binary versions of the program.
PHCpack was originally designed to implement the development
of polynomial homotopies exploiting structure in order to
better approximate all isolated solutions.
The package also exports the numerical irreducible decomposition,
and can compute all positive dimensional solution sets of a system.
PHCpack is open source and free software;
you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; version 3 of the License.
The most recent version of the source code is at
github.
Also executable versions of the program are available from that site.
Release 2.4.85 of PHCpack contains the following files:
interfaces to PHCpack
There are interfaces for Python (based on the C interface),
Maple, MATLAB (or Octave), SageMath, and Macaulay2.
-
If you are familiar with python, then
phcpy may be just right for you.
The pdf of the documentation is here.
- An interface with Maple is PHCmaple,
developed in collaboration with Anton Leykin,
archived at
github.
- Another interface to PHCpack is described by
Yun Guan and Jan Verschelde:
PHClab: A MATLAB/Octave interface to PHCpack.
Download version 1.0.4 (12 September 2014) of
PHClab here.
Take a look at
the Poster.
-
Thanks to the efforts of Marshall Hampton, Kathy Piret, and William Stein,
PHCpack is one of the experimental packages
in SAGE .
-
With Elizabeth Gross and Sonja Petrovic (with contributions
from Anton Leykin), we developed an interface to Macaulay2:
PHCpack.m2
and its documentation
PHCpackDoc.m2,
described in
PHCpack in Macaulay2.
