$\begin{bmatrix}
    x & y & d & \dots  & f \
    b & a & c & \dots  & e \
    \vdots & \vdots & \vdots & \ddots & \vdots \
    \infty & \phi & \alpha & \dots  & \xi
\end{bmatrix}$

I got it

`$\begin{bmatrix}    x & y & d & \dots  & f \    b & a & c & \dots  & e \    \vdots & \vdots & \vdots & \ddots & \vdots \    \infty & \phi & \alpha & \dots  & \xi\end{bmatrix}$`

you put ` before and after the code, make sure there are no enters in the code otherwise it won't work but the latex will still work xD

There are also different supported delimiters for a matrix, given by `bmatrix` (square brackets `[]`), `vmatrix` (vertical pipes `||`), `pmatrix` (parentheses `()`), `Bmatrix` (curly braces `{}`), and `Vmatrix` (double vertical pipes (`|| ||`).

Examples:
`\begin{bmatrix}1&0\0&1\end{bmatrix}` $\implies\begin{bmatrix}1&0\0&1\end{bmatrix}$

`\begin{vmatrix}1&0\0&1\end{vmatrix}` $\implies\begin{vmatrix}1&0\0&1\end{vmatrix}$

`\begin{pmatrix}1&0\0&1\end{pmatrix}` $\implies\begin{pmatrix}1&0\0&1\end{pmatrix}$

`\begin{Bmatrix}1&0\0&1\end{Bmatrix}` $\implies\begin{Bmatrix}1&0\0&1\end{Bmatrix}$

`\begin{Vmatrix}1&0\0&1\end{Vmatrix}` $\implies\begin{Vmatrix}1&0\0&1\end{Vmatrix}$

You can also consider changing the environment to `array` which is quite handy for making tables with arbitrary vertical/horizontal lines, then add delimiters.

Silly example:
`\left.\begin{array}{|c|r}\text{what}&\text{is}\\hline\text{going}&\text{on}\end{array}\right\}` gives
$$\left.\begin{array}{|c|r}
\text{what}&\text{is}\
\hline
\text{going}&\text{on}
\end{array}\right\}$$
