我一直在使用create-large-nodes nicematrix环境选项与 的组合name suffix=-large，其用法类似于tikz选项，在code-after nicematrix，就像在nicematrix 包文档但它返回以下错误消息：
! 包 pgf 错误：没有已知名为 nm-1-1-1-large-large 的形状。
看来这些nicematrix选项无法正常工作。有人知道发生了什么吗？
MWE 如下。

答案1
1-1该命令在单元格中创建的块\Block的名称1-1为nicematrix（这在的文档中没有明确说明nicematrix：我可能会更改这一点）。
因此，您可以使用它在该块上添加支架（我们不需要“大节点”）：
\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{nicematrix}
\usetikzlibrary{decorations.pathreplacing}
\begin{document}
\begin{small}
\begin{align}
\boldsymbol{\mathcal{F}}^{i} = & %
\begin{bNiceArray}{CCCCCC}[%
margin,
extra-margin=2pt,
code-after =
{ \begin{tikzpicture}
\draw [decorate,decoration = brace]
([yshift=1.5mm]1-1.north west) to
([yshift=1.5mm]1-1.north east) ;
\end{tikzpicture} } ]
\Block{3-3}{\boldsymbol{\mathcal{F}}_{\boldsymbol{\aleph}}^{i}} & & & \mathtt{f}_{1\,(\varpi+1)} & \cdots & \mathtt{f}_{1\,\eta} %
\\
& & & \vdots & \vdots & \vdots %
\\
& & & \mathtt{f}_{\varpi\,(\varpi+1)} & \cdots & \mathtt{f}_{\varpi\,\eta} %
\\
\mathtt{f}_{(\varpi+1)\,1} & \cdots & \mathtt{f}_{(\varpi+1)\,\varpi} & \mathtt{f}_{(\varpi+1)\,(\varpi+1)} & \cdots & \mathtt{f}_{(\varpi+1)\,\eta} %
\\
\vdots & \vdots & \vdots & \vdots & \ddots & \vdots %
\\
\mathtt{f}_{\eta\,1} & \cdots & \mathtt{f}_{\eta\,\varpi} & \mathtt{f}_{\eta\,(\varpi+1)} & \cdots & \mathtt{f}_{\eta\,\eta} %
\end{bNiceArray}%
\end{align}
\end{small}
\end{document}

我发现了这个问题的根源：我的 MikTeX 版本太旧了。更新后，这段代码可以正常工作。
