方程组

\begin{cases}
x+y+z=10\\
x+2y+3z=20\\
x+4y+5z=30
\end{cases}

需要改为

\left\{
\begin{matrix}
x+y+z=10 \\
x+2y+3z=20 \\
x+4y+5z=30 \\
\end{matrix}
\right

矩阵

\left(
\begin{array}{ccc}
1 & 2 & 3\\
4 & 5 & 6\\
7 & 8 & 9\\
\end{array}
\right)

需要改为

\left(
\begin{matrix}
1 & 2 & 3\\
4 & 5 & 6\\
7 & 8 & 9\\
\end{matrix}
\right)

连续等式对齐

\begin{align}
	f(x)  & ={\frac{1}{1+e^{-x}}}                               \\
	f'(x) & ={\frac{1}{1+e^{-x}}}\cdot{\frac{e^{-x}}{1+e^{-x}}}
\end{align}

改为

\begin{matrix}
	f(x)  ={\frac{1}{1+e^{-x}}} \\
	f'(x) ={\frac{1}{1+e^{-x}}}\cdot{\frac{e^{-x}}{1+e^{-x}}}
\end{matrix}

不能用&=,且不会左对齐
