# NAG Library Routine DocumentF06DBF

Note:  before using this routine, please read the Users' Note for your implementation to check the interpretation of bold italicised terms and other implementation-dependent details.

## 1  Purpose

F06DBF broadcasts an integer scalar into an integer vector.

## 2  Specification

 SUBROUTINE F06DBF ( N, CON, X, INCX)
 INTEGER N, CON, X(*), INCX

## 3  Description

F06DBF performs the operation
 $x←α,α,…,αT,$
where $x$ is an $n$-element integer vector scattered with stride INCX.

None.

## 5  Parameters

1:     N – INTEGERInput
On entry: $n$, the number of elements in $x$.
2:     CON – INTEGERInput
On entry: the scalar $\alpha$.
3:     X($*$) – INTEGER arrayOutput
Note: the dimension of the array X must be at least $\mathrm{max}\phantom{\rule{0.125em}{0ex}}\left(1,1+\left({\mathbf{N}}-1\right)×{\mathbf{INCX}}\right)$.
On exit: the vector $x$. ${x}_{\mathit{i}}$ will be stored in ${\mathbf{X}}\left(1+\left(\mathit{i}-1\right)×{\mathbf{INCX}}\right)$, for $\mathit{i}=1,2,\dots ,{\mathbf{N}}$.
Intermediate elements of X are unchanged.
4:     INCX – INTEGERInput
On entry: the increment in the subscripts of X between successive elements of $x$.
Constraint: ${\mathbf{INCX}}>0$.

None.

Not applicable.

None.

None.
