A first version of the package is already available in the project's download section. A paper with a manual will soon appear at the arXiv.
Installation
e6tensors_full
Download version x.y.z at the dowload page. Extract the tarball
tar xzf e6tensors_fullx.y.z.tar.gz
The contained file "E6Tensors.m" is ready for usage in Mathematica. Mind that is has a size of roughly 150 MB. Therfore, be sure to provide enough RAM for Mathematica. See the "examples.nb" file for some neat examples.
e6tensors_small
This version has the advantage of a smaller download size. Download it at the dowload page and extract the archiv
tar xzf e6tensors_fullx.y.z.tar.gz
Switch your working directory to
cd e6tensors_small
and enter the following command. This may take some time!
./install.sh
If your Mathematica command line version is not called math , you should change that in install.sh. The script calls Mathematica and runs create_E6Tensors.m. If you want to use more than one CPU change
LaunchKernels[1]
in create_E6Tensors.m to the right value. Be sure to provide enough subkernel licences. On an i5 quadcore machine using four subkernels this installation takes about half an hour.
Now, your version is perfectly equivalent to e6tensors_full.
