In this blog, I will show you how to make a matrix with mathjax. It will help you better blog about linear algebra.

Code:

$$
\begin{bmatrix}
	1 & 2 & 1 \\
	3 & 8 & 1 \\
	0 & 4 & 1 \\
\end{bmatrix}
$$

Result：

$$
\begin{bmatrix}
    1 & 2 & 1 \\
    3 & 8 & 1 \\
    0 & 4 & 1 \\
\end{bmatrix}
$$

Replaced with {Bmatrix}, it becomes

$$
\begin{Bmatrix}
    1 & 2 & 1 \\
    3 & 8 & 1 \\
    0 & 4 & 1 \\
\end{Bmatrix}
$$

Replaced with {vmatrix}, it becomes

$$
\begin{vmatrix}
    1 & 2 & 1 \\
    3 & 8 & 1 \\
    0 & 4 & 1 \\
\end{vmatrix}
$$

Replaced with {Vmatrix}, it becomes

$$
\begin{Vmatrix}
    1 & 2 & 1 \\
    3 & 8 & 1 \\
    0 & 4 & 1 \\
\end{Vmatrix}
$$

Replaced with {matrix}, it becomes

$$
\begin{matrix}
    1 & 2 & 1 \\
    3 & 8 & 1 \\
    0 & 4 & 1 \\
\end{matrix}
$$

Replaced with {patrix}, it becomes

$$
\begin{pmatrix}
    1 & 2 & 1 \\
    3 & 8 & 1 \\
    0 & 4 & 1 \\
\end{pmatrix}
$$

 

How to make an augmented matrix?

Code:

$$
\left [
    \begin {array} {cc|c}
      1&2&3\\
      4&5&6
    \end {array}
\right ] 
$$

Result:

$$
\left [
    \begin {array} {cc|c}
      1&2&3\\
      4&5&6
    \end {array}
\right ] 
$$
