The `physics3` Package
======================

This package defines commands for typesetting math formulae faster and
more simply. `physics3` is a modularized package, each module provides its
own function while `physics3.sty` itself only provides very few functions.
Therefore you can load modules separately after loading `physics3`.

Modules of `physics3` 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;
