# The `physics2` package This package defines commands for typesetting math formulae faster and more simply. `physics2` is a modularized package, each module provides its own function while `physics2.sty` itself only provides very few functions. Therefore you can load modules separately after loading `physics2`. Modules of `physics2` provide the following supports: - Automatic braces; - Dirac bra-ket notation; - Easy way to typeset diagonal matrices and matrices with similar entries; - Double cross and double dot (binary) operators for tensors; **Welcome to pull requests [here](https://github.com/AlphaZTX/physics2/pulls).** ## License This work may be distributed and/or modified under the conditions of the [LaTeX Project Public License](http://www.latex-project.org/lppl.txt), either version 1.3c of this license or (at your option) any later version.
