Diffcoeff 包 - 高阶导数

Diffcoeff 包 - 高阶导数

我想使用差异系数软件包版本 5.1 用于编写导数的排序，如下例所示。虽然示例很简单，但无法编译。问题出在表达式\diff[n+1]yx和上\diffp[n+1]yx。

这些表达式是从软件包手册的第 12 页和第 13 页复制而来的。这有什么问题？我担心库本身或 Koma-script 有问题。

如果我scrbook用articledocumentclass 替换它，它就会起作用。

MNWE：

\documentclass[12pt]{scrbook}
\listfiles
\usepackage{diffcoeff}   

\begin{document}
  \[\diff[2]yx\]
  x\[\diff[n+1]yx.\]

  \[ \diffp[2]yx\] 
  \[\diffp[n+1]yx. \]
\end{document}

我忽略了一个初始化语句。\__diffcoeff_evaluate:NN第 531 行的例程diffcoeff v5.1需要语句

\seq_clear:N \l_tmpa_seq
\seq_clear:N \l_tmpb_seq

打开后立即{。（显然scrbook也使用\l_tmpa_seq。您的示例使用例如类进行编译。）我将很快将此更正（以及更好地处理空微分变量参数）article的 v5.2 上传到 CTAN。diffcoeff
