# 如何在 LaTeX 中建立矩陣

這是由 21 集系列中的第 16 支影片，製作者為 [Vincent Knight 博士](http://bit.ly/186ai3Z) 卡地夫大學的。在這支影片中，Vince 示範如何使用 `amsmath` 套件與 `\pmatrix` （用於帶大括號的矩陣）， `\matrix` （用於沒有括號的矩陣），以及 `\vmatrix` （用於表示矩陣行列式）的指令。以下是最後一個範例的程式碼：

```latex
$$
\begin{vmatrix}
a&b\\
c&d\\
e&f\\
\end{vmatrix}
$$
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-tw/wen-yu-da/45-how-to-create-matrices-in-latex.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
