This package is available at
http://www.icm.tu-bs.de/ag_algebra/software/distler/radiroot
in form of a gzipped tar-archive. For the installation instructions see Chapter Installing a GAP Package in the GAP Reference Manual. Normally you will unpack the archive in the 'pkg' directory of your GAP-Version by typing:
bash> tar xfz radiroot.tar.gz # for the gzipped tar-archive
To use the Radiroot Package you have to request it explicitly. This is done by calling
gap> LoadPackage("radiroot"); ----------------------------------------------------------------------------- Loading RadiRoot 1.0 (Roots of a Polynomial as Radicals) by Andreas Distler (a.distler@tu-bs.de). ----------------------------------------------------------------------------- true
The LoadPackage
command is described in Section LoadPackage in
the GAP Reference Manual.
If you want to load the Radiroot package by default, you can put the
LoadPackage
command into your .gaprc
file (see Section The .gaprc file in the GAP Reference Manual).
The package Alnuth 2.0 or higher has to be available with its full functionality to use Radiroot.
A dvi file is created to display roots. As default the package uses the
command latex
searched for in your system programs to create the dvi file
and the command xdvi
to start the dvi viewer. If you can't use this
settings you will have to change the function RR_Display
in the file
Strings.gi
in the subdirectory lib
.
