Elements of the row matrix are located along a row according to the sequence. Latex has more than one package to define the matrix. In this tutorial, Row Matrix is defined using amsmath and physics packages.

In this case, a row must be created in the latex environment. And according to the sequence, the elements of the matrix have to be inserted in this latex environment.

`... & ... & ... & ...`

You notice syntax above.** A row** is taken here and **four elements** are inserted in it. & symbol is used to separate each element of the row.

## amsmath package for row matrix

To be bound by brackets on both sides of the matrix, bmatrix must be passed as an argument in a latex environment.

```
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$$
\begin{bmatrix}
a_{1} & a_{2} & \cdots & a_{n}
\end{bmatrix}
$$
\end{document}
```

**Output :**

## physics package for row matrix

There are more than one process for defining a matrix in a physics package. However, the easiest process is to define matrix using \mqty command.

```
\documentclass{article}
\usepackage{physics}
\begin{document}
$$
\mqty[a_{1} & a_{2} & \cdots & a_{n}]
$$
\end{document}
```

**Output :**
