A row matrix is a matrix that has only one row.

## What is a row of a matrix?

In mathematics, a row matrix is a type of matrix that has a single row. But the number of columns could be more than one. Therefore, if the matrix is in the order of 1 x n, then it is a row matrix. The elements are arranged in an order such that they represent a single row in the matrix.

## How many column contains in row matrix?

The row matrix has one row and n number of columns. The number of columns in a row matrix is equal to the number of elements.

## What is the size of a row matrix?

Size of a matrix = number of rows × number of columns. It can be read as the size of a matrix and is equal to number of rows “by” number of columns.

## What is a 1 row matrix called?

Matrices with a single row are called row vectors, and those with a single column are called column vectors. A matrix with the same number of rows and columns is called a square matrix. A matrix with an infinite number of rows or columns (or both) is called an infinite matrix.
