我在创建以下矩阵时遇到了麻烦。我尝试了这里几篇文章中的技巧，但无法获得良好的结果。最好的选择似乎是包nicematrix，但我正在使用a0poster类，而包无法正常工作。我想我要pspicture画出方框，但我的结果看起来很糟糕。
最好突出显示 B，但不必像图中所示那样用对角线进行阴影处理。0 也很不错，但似乎很难很好地对齐，必要时可以忽略。底部的“粘合向量”框似乎确实弄乱了矩阵其余部分的对齐。
任何关于如何正确处理此图的代码或建议都将不胜感激。也许tikz这里有必要？
编辑：下面是我环境中的一个最小工作示例。我认为最好的解决方案是使用nicematrix，所以我把它包括进去了。我认为这个例子的问题在于与不兼容tikz。我在序言中包括了一些解决方法代码，这些代码来自nicematrix文档的第 21 页2。我确实需要 tikz，并且在此文档中包含了我需要编译的两个基本图表。
这里给出的具体错误nicematrix是The option "code-after" is unknown or meaningless in the context.，我在 macOS 上使用 TexShop 4.44 并正在编译Tex -> DVI。在我的系统上（忽略错误），下面的代码显示为
