저는 이 예제를 2008년에 만들었고 컴파일했습니다(texample.net).
코드를 다시 컴파일하려고 했지만 성공하지 못했으며 오류를 찾을 수 없습니다.
이제 일부 노드가 정의되지 않았습니다. 문제가 있는 줄에 댓글을 달았습니다.

이제 나는 얻는다
첫 번째 줄에 주석을 달았습니다.

답변1
또는 \node에 명령을 넣는 것이 실제로 지원되는지 잘 모르겠습니다 . 어쨌든 노드에 스타일을 부여하는 데 사용하는 것 같습니다. 더 간단한 방법이 있습니다. 대신에matrix of nodesmatrix of math nodes
\node[node style sp] {a_{22}};
그냥 말해
|[node style sp]| a_{22}
이는 현재 매뉴얼(v3.1.5)에 문서화된 방법이며 작동합니다.
