pmatrix 的問題

我嘗試按如下方式使用 pmatrix：

\begin{equation}\label{Eq.11}
J =
\begin{pmatrix}
  \frac{\partial c_{1}(t+1)}{\partial c_{1}(t)} & \frac{\partial c_{1}(t+1)}{\partial c_{2}(t)} & \cdots & \frac{\partial c_{1}(t+1)}{\partial c_{L}(t)} \\
  \frac{\partial c_{2}(t+1)}{\partial c_{1}(t)} & \frac{\partial c_{2}(t+1)}{\partial c_{2}(t)} & \cdots & \frac{\partial c_{2}(t+1)}{\partial c_{L}(t)} \\
  \vdots  & \vdots  & \ddots & \vdots  \\
  \frac{\partial c_{L}(t+1)}{\partial c_{1}(t)} & \frac{\partial c_{L}(t+1)}{\partial c_{2}(t)} & \cdots & \frac{\partial c_{L}(t+1)}{\partial c_{L}(t)} 
 \end{pmatrix}.
\end{equation}

出現以下錯誤：

! Extra \right.\endpmatrix -> \endmatrix \right ) \end{pmatrix}
! Missing $ inserted.<inserted text>$ \end{pmatrix}
! Missing } inserted.<inserted text>} \end{pmatrix}
! You can't use `\eqno' in math mode.\endmathdisplay@a ...\df@tag \@empty \else \veqno\alt@tag \df@tag \fi \ifx ... \end{equation}
! Missing \right. inserted.<inserted text>\right . \end{equation}
! Missing \endgroup inserted.<inserted text>\endgroup \end{equation}

該程式碼在其他文件中運作良好，但我正在處理的最後一個文件由多個文件組成，每個文件代表文件中的一個章節。

任何建議將不勝感激。

謝謝

請經常發帖完全的產生錯誤的文檔。特別是，它允許您檢查您發布的片段實際上是否產生了錯誤。您問題中的片段不會產生錯誤，而且錯誤訊息也不是完整的 TeX 錯誤訊息。

不過我猜你的真實文件是這樣的，它會產生類似的錯誤，這裡我顯示完整的 TeX 錯誤，它比過濾視圖提供更多資訊：

\documentclass{article}

\usepackage{amsmath}
\begin{document}

$\left(     % unfinished math expression
\begin{equation}\label{Eq.11}
J =
\begin{pmatrix}
  \frac{\partial c_{1}(t+1)}{\partial c_{1}(t)} & \frac{\partial c_{1}(t+1)}{\partial c_{2}(t)} & \cdots & \frac{\partial c_{1}(t+1)}{\partial c_{L}(t)} \\
  \frac{\partial c_{2}(t+1)}{\partial c_{1}(t)} & \frac{\partial c_{2}(t+1)}{\partial c_{2}(t)} & \cdots & \frac{\partial c_{2}(t+1)}{\partial c_{L}(t)} \\
  \vdots  & \vdots  & \ddots & \vdots  \\
  \frac{\partial c_{L}(t+1)}{\partial c_{1}(t)} & \frac{\partial c_{L}(t+1)}{\partial c_{2}(t)} & \cdots & \frac{\partial c_{L}(t+1)}{\partial c_{L}(t)} 
 \end{pmatrix}.
\end{equation}

\end{document}

出現以下錯誤（在 TeX 中總是首先查看第一個錯誤，因為在這種情況下，以下所有錯誤都是虛假的）
