# getRow¶

## Purpose¶

Returns a specified row from a matrix.

## Format¶

y = getRow(a, row)
Parameters
• a (NxK matrix) – data

• row (scalar) – The row of the matrix to extract

Returns

y (1xK row vector) – extracted data

## Examples¶

First create a matrix, a:

a = rndn(10, 10);


Now you can assign a variable y to be equal the third row of a with either of the following statements.

y = getRow(a, 3);


or

y = a[3, .];


While both statements will produce the same result, the first may make for code that is easier to read and interpret.

## Remarks¶

getRow() is designed to give an alternative access to rows in a matrix than indexing the matrix by brackets.
