Qiitaで可換図式を描く

Last updated at Posted at 2017-06-02

$\require{AMScd}$

方法

QiitaはMathJaxを使用しているのでAMScdを使って図が描ける。記事の最初に$\require{AMScd}$と書くことでAMScdが使用できる。

```math
\begin{CD}
F(B) @>F(f)>> F(A) \
@VbVV @VaVV \
B @>f>> A
\end{CD}


と書くと以下の図が表示される。詳しい使い方はAMScdで検索してほしい。

```math
\begin{CD}
F(B) @>F(f)>> F(A) \\
@VbVV @VaVV \\
B @>f>> A
\end{CD}
