# Named tensor notation in LaTeX
This style file provides macros for named tensor notation. Please see
the paper [Named Tensor Notation](https://arxiv.org/abs/2102.13196)
for background on this notation.
To use the style file, put
\usepackage{namedtensor}
into the preamble of your LaTeX source file (after
`\documentclass{article}` but before `\begin{document}`).
We write axis names in sans-serif font. To make this easier,
`\name{axis}` prints the axis name "axis", and `\ndef{\ax}{axis}`
defines a macro `\ax` that prints the axis name "axis".
Binary operators
- Use `A \ndot{\ax} B` for contractions. You can use `\\` to stack up
several names.
- You can use `\nbin` to make new binary operators. For example, `A
\nbin{\ax}{\star} B` gives you a star operator with "axis" written
under it.
Functions
- Use `\nsum{\ax} A` for summation over a named axis.
- You can use `\nfun` to make new functions. For example,
`\nfun{\ax}{qux} A` defines a function "qux" with "axis" written
under it.
