 installiert sein.
 Ein

\noun default
-Diagramm wird erzeugt,
 indem der Befehl

 in eine Formel eingegeben wird.
 Man kann anschließend neue Matrix-Spalten und Zeilen wie bei normalen Matrizen einfügen.

 Wenn Ihr Dokument ein Stichwortverzeichnis hat und eine der AMS Theorem-Module verwendet wird,
 muss die Option

 zu den Dokumentklassenoptionen in den Dokument-Einstellungen hinzugefügt werden.
 Dies ermöglicht die Verwendung des Zeichens '!' in Stichworten (wird für Untereinträge benötigt),
 kann aber zu Problemen mit den Align-Umgebungen führen (die im Abschnitt
