# Tensor manipulation in GPL Maxima

@article{Toth2005TensorMI, title={Tensor manipulation in GPL Maxima}, author={V. Toth}, journal={ArXiv}, year={2005}, volume={abs/cs/0503073} }

GPL Maxima is an open-source computer algebra system based on DOE-MACSYMA. GPL Maxima included two tensor manipulation packages from DOE-MACSYMA, but these were in various states of disrepair. One of the two packages, CTENSOR, implemented component-based tensor manipulation; the other, ITENSOR, treated tensor symbols as opaque, manipulating them based on their index properties. The present paper describes the state in which these packages were found, the steps that were needed to make the… CONTINUE READING
