\emph on
l
\emph default
は左寄せ，
\emph on
c
\emph default
は中央揃え，

は右寄せを意味します．たとえば，第1列が左寄せで第2列と第3列が中央揃え，第4列が右揃えの
\begin_inset Formula $4\times4$

行列を作成するには，水平配置のところに

に関しては，母音の前に引用符を挿入する方法の方がよいでしょう．ウムラウトのある数式部分がドイツ語に指定してあれば，\SpecialChar LaTeX
は，引用符と母音をまとめて一つの文字として取り
扱います．
\series bold

と違い，この方法では，以下の例に示すように「本物の」ウムラウトが作られます．

に比べて良いもう一つの利点は，上記のアクセントコマンドが

のに対し，ウムラウトは直接数式中テキストに変換されることです．(アクセントコマンドによる)アクセント付き文字を数式中テキストに変換すると，アクセントの下にある文
字しか変換されません．これは，たとえばイタリック体やボールド体への変換など，他のすべての変換に関しても言えることです．

\begin_layout Standard
数式全体をボールド体にしようとすると，前節の
\series bold

\series default
コマンドは，ギリシャ文字の小文字に対しては機能しないので，使用することができません．さらにこのコマンドは，以下の式のように，ラテン文字をつねにアップライト体に印

\end_layout

\begin_layout Standard
\begin_inset Formula 
\[
\mathbf{\int_{n}^{2}f(\theta)=\Gamma}\qquad\textrm{\textbackslash mathbfを使用した数式}

\end_inset


\end_layout

\begin_layout Standard
この数式を正しく表示するには，以下のように，
\series bold

コマンドを使用します．
\begin_inset Formula

\begin_layout Standard
これらのコマンドによって生成される実際の書体寸法は，文書の書体寸法に依存し，文書の書体寸法が
\series bold

\backslash
normalsize
\series default
コマンドに設定されます．他のコマンドは，
\series bold

\backslash
normalsize
\series default
を基準として拡大ないし縮小されます．しかしながら，書体寸法は一定の値を越えることができないようになっています．たとえば，文書書体寸法が12
\begin_inset space \thinspace{}
\end_inset

ptであるならば，
\series bold

\backslash
Huge
\series default
コマンドは
\series bold

\backslash

\series default
コマンドと同じ大きさに落とされます．
\end_layout

\begin_layout Standard
ある場所以降のすべての数式と本文文字を変更するには，書体寸法コマンドを\SpecialChar TeX
モードで挿入します．元の書体寸法に戻すには，数式の後に\SpecialChar TeX
モードで
\series bold

\backslash

\series default
コマンドを挿入します．
\end_layout

\begin_layout Standard
数式内では，以下の寸法コマンドまたはツールバーボタン
\begin_inset Info

\end_inset

を使用して，寸法を変更することができます．

一般的に，数式表現では変数は

は
\begin_inset Formula $s\cdot i\cdot n$

であるかのように誤解させる恐れがあるためです．そのために，定義済み関数が存在し，これらは先行する要素よりも少し離れて配置されます．定義済み関数は，関数名の前にバ

以下は，別行立て数式での派生型です．
\begin_inset Formula 
\begin{align*}
\underline{\textrm{コマンド}\raisebox{-0.9mm}{}} &  & \underline{\textrm{出力}}\\
\mathrm{a\backslash mod\textrm{␣}b} &  & a\mod b\\

\end_layout

\begin_layout Standard
行内数式では，すべての派生型で，関数名の前の余白がすこし小さく設定されます．既定では，剰余関数は，続く一文字目だけを考慮します．二文字以上を使いたい時には，下記

括弧で囲みます．
\begin_inset Formula 
\begin{align*}
\underline{\textrm{コマンド}\raisebox{-0.9mm}{}} &  & \underline{\textrm{出力}}\\

自己定義コマンドは，複雑な表現を使うときに特に便利です．たとえば，文書中で二次方程式を扱っているとすると，同じような解の形が何度も出てきます．二次方程式の一般型
は，
\begin_inset Formula 
\[
0=\lambda^{2}+p\lambda+q
\]

\end_inset

であり，その解の一般型は
\begin_inset Formula 
\[
\lambda_{1,2}=-\frac{p}{2}\pm\sqrt{\frac{p²}{4}-q}
\]

\end_inset


\end_layout

\begin_layout Standard
です．
\begin_inset Formula $\lambda$
\end_inset

・
\begin_inset Formula $p$
\end_inset

・
\begin_inset Formula $q$
\end_inset

の3つのパラメータを指定することが必須であり，
\begin_inset Formula $\lambda$
\end_inset

の指数をオプションとして与えることができるような，解の公式のコマンドを定義するには，以下のような\SpecialChar LaTeX
プリアンブル行を加えます．
\begin_inset Newline newline

\end_layout

\begin_layout Standard
新コマンドを定義する方法は，たとえば\SpecialChar LaTeX
中で分数は
\series bold

\backslash
frac{分子}{分母}
\series default
の形で入れなくてはならないことなど，使用するすべての\SpecialChar LaTeX
コマンドの書式を知っている必要があるので，直感的ではありません．さらに，定義中で中括弧を入れ忘れることはよく
あり，それをやってしまうと，\SpecialChar LyX
からは新コマンドが何をやらかしているか確認しにくくなってしまいます．これらの問題を回避するために，\SpecialChar LyX
は，
\series bold

\backslash
newcommand
\series default
コマンドの代わりに，数式マクロを使う方法を提供しています．
\end_layout

\begin_layout Standard
数式マクロは，
\family sans
挿入\SpecialChar menuseparator
数式\SpecialChar menuseparator
マクロ
\family default
メニューか，ツールバーボタンの
\begin_inset Info
type  "icon"
arg   "math-macro newmacroname_newcommand"
\end_inset

で作ることができます．すると，数式マクロツールバーが表示されるとともに，マクロを定義した箇所に以下のようなボックスが現れます．
\begin_inset Newline newline
\end_inset


\begin_inset space \hspace*{\fill}

\begin_inset Graphics

\end_inset


\backslash
newmacronameが既定のマクロ名として現れますが，意味のある名称に変更するべきでしょう．欲しい数式は一つ目の青枠の中に入れます．引数を置く場所は，
\series bold

\backslash
#1
\series default
のように
\series bold

\backslash
#引数番号
\series default
というコマンドで入力するか，マクロツールバーボタンの
\begin_inset Info
type  "icon"
arg   "math-macro-add-param"
\end_inset

を使用します．引数位置は赤で表示されます．引数は，最大で9つまでとることができます．非必須引数は，ツールバーボタンの
\begin_inset Info
type  "icon"
arg   "math-macro-add-optional-param"
\end_inset

で作ることができます．最初の必須引数は，ツールバーボタンの
\begin_inset Info
type  "icon"
arg   "math-macro-make-optional"
\end_inset

を使って，非必須引数にすることができます．二つ目の青枠には，\SpecialChar LyX
中でのマクロの表示のしかたを定義することができます．通常は，定義したとおりに表示された方が便利なので
，この枠は空白にしておきます．しかし，画面の過半を占拠してしまうようなマクロを作ってしまった場合には，たとえばこの枠に
\begin_inset Newline newline
\end_inset


\series bold
qG: 
\backslash

\series bold

,

\series bold

\backslash

\backslash

\begin_inset Newline newline
\end_inset


\series default
のように入れることができます．このようにすると，マクロ名と引数のみが\SpecialChar LyX
上に表示され，見通しが良くなります．一方，出力での数式は，最初の枠で定義したように表示されま
す．
\begin_inset Newline newline
\end_inset

さらに，数式中のマクロ表示は，マクロの中にカーソルを置いて，
\family sans
表示\SpecialChar menuseparator
数式マクロを展開(畳む)
\family default
メニューを使うことで，マクロ毎に変えることができます．
\end_layout

\begin_layout Standard
マクロを使うには，数式中にマクロ名をコマンドとして入れます．上記の例では，
\series bold

\backslash
qG
\series default
とします．このマクロは，\SpecialChar LyX
中では以下のように表示されます．
\begin_inset Newline newline
\end_inset


\begin_inset space \hspace*{\fill}

\begin_inset Formula $x$
\end_inset

・
\begin_inset Formula $\ln(x)$
\end_inset

・
