1  Purpose

F06FBF broadcasts a real scalar into a real vector.

2  Specification

SUBROUTINE F06FBF ( N, CON, X, INCX)
INTEGER  N, INCX
REAL (KIND=nag_wp)  CON, X(*)

3  Description

F06FBF performs the operation
xα,α,,αT,  
where x is an n-element real vector.

4  References

None.

5  Parameters

1:     N – INTEGERInput
On entry: n, the number of elements in x.
2:     CON – REAL (KIND=nag_wp)Input
On entry: the scalar α.
3:     X* – REAL (KIND=nag_wp) arrayOutput
Note: the dimension of the array X must be at least max1, 1+N-1 ×INCX .
On exit: the vector x. xi will be stored in X1+i-1×INCX, for i=1,2,,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: INCX>0.

6  Error Indicators and Warnings
