Latex --- plus subscript, all kinds of common symbols, formulas typesetting

_It represents standard, ^represents the landmark.

If a special symbol is inserted in the text need to add $$

    eg:          $G_{s}$   

    Effect: Gs

2 If the special symbols in the formula plus added directly on the line

\begin{align}  % 公式
  G_{s} \cup G_{e} = G_{s}
  G_{s} \cap G_{e} = G_{e}
\end{align}

Formula into a plurality of rows with braces, the effect is as follows:

LaTex editor as follows:

\begin{equation}
\label{eq6}
[x_{i}]=\left\{
\begin{aligned}
x_{ac} & , & \mu_{a}(x_{i})\geq \mu_{b}(x_{i}), \\
x_{bc} & , & \mu_{a}(x_{i})< \mu_{b}(x_{i}).
\end{aligned}
\right.
\end{equation}

\begin{equation}
\label{eq6}
[x_{i}]=\left\{
\begin{aligned}
x_{ac} & , & \mu_{a}(x_{i})\geq \mu_{b}(x_{i}), \\
x_{bc} & , & \mu_{a}(x_{i})< \mu_{b}(x_{i}).
\end{aligned}
\right.
\end{equation}

公式对齐问题

基础知识：

换行：  \\

去掉一行公式的标号，在后面加 \nonumber即可

1 公式居中

\begin{gather*}
  f_{FGM-S} = C(C(f_{e}^{i}) \ast C^{2}(f_{s}^{i-1}))\\
  f_{FGM-E} = C(A(Cat(C(f_{s}^{i}), C^{2}(f_{e}^{i-1})))
\end{gather*}

加星会无编号

\begin{gather*}
  f_{FGM-S} = C(C(f_{e}^{i}) \ast C^{2}(f_{s}^{i-1}))\\
  f_{FGM-E} = C(A(Cat(C(f_{s}^{i}), C^{2}(f_{e}^{i-1})))
\end{gather*}

\begin{gather}
  f_{FGM-S} = C(C(f_{e}^{i}) \ast C^{2}(f_{s}^{i-1}))\\
  f_{FGM-E} = C(A(Cat(C(f_{s}^{i}), C^{2}(f_{e}^{i-1})))
\end{gather}

不加星会有编号，在latex中可以看到

\begin{gather}
  f_{FGM-S} = C(C(f_{e}^{i}) \ast C^{2}(f_{s}^{i-1}))\\
  f_{FGM-E} = C(A(Cat(C(f_{s}^{i}), C^{2}(f_{e}^{i-1})))
\end{gather}

2 按照等号对齐

\begin{align}
    sum &= a+b+c+d \\
    sub &= a-b
\end{align}
加入&在等号前

\begin{align}
    sum &= a+b+c+d \\
    sub &= a-b
\end{align}

3 等式居左

\begin{flalign}
    &a&
    &a& \\
    &a& \nonumber \\
\end{flalign}

   \begin{flalign}

    &表达式&

   &表达式& \\

    &表达式& \nonumber \\

\end{flalign}

4 整体左对齐、

\begin{eqnarray}
&&f_{s}^{i-1} = C(f_{FFM-S}^{i-1} + f_{FGM-S}^{i-1})\\
&&= C(C(f^{i-1}_{s})(f_{s}^{i-1})))\\
&&f_{e}^{i-1} = C(f_{FFM-E}^{i-1} + f_{FGM-E}^{i-1}) \\
&&= C(C(f^{i-1}_{e})(f_{e}^{i-1}))) )
\end{eqnarray}

\begin{eqnarray}
&&f_{s}^{i-1} = C(f_{FFM-S}^{i-1} + f_{FGM-S}^{i-1})\\
&&= C(C(f^{i-1}_{s})(f_{s}^{i-1})))\\
&&f_{e}^{i-1} = C(f_{FFM-E}^{i-1} + f_{FGM-E}^{i-1}) \\
&&= C(C(f^{i-1}_{e})(f_{e}^{i-1}))) )
\end{eqnarray}
