To be able to create

\noun default
diagrams,
the \SpecialChar LaTeX
-package
\series bold
feyn

must be installed.
A
\noun on
Feynman
\noun default
diagram is created by inserting the command
\series bold
\backslash

in a formula.
Then you are able to add new matrix columns and rows like a normal matrices.

\begin_layout Standard
As matrix entry,
one can enter commands that act as

If you have an index list in your document and use one of the AMS theorem modules,
you have to add the option
