1 Purpose

f06hbf broadcasts a complex scalar into a complex vector.

2 Specification

Fortran Interface
Subroutine f06hbf ( n, con, x, incx)
Integer, Intent (In) :: n, incx
Complex (Kind=nag_wp), Intent (In) :: con
Complex (Kind=nag_wp), Intent (Inout) :: x(*)
C Header Interface
#include <nag.h>
void  f06hbf_ (const Integer *n, const Complex *con, Complex x[], const Integer *incx)
The routine may be called by the names f06hbf or nagf_blas_zload.

3 Description

f06hbf performs the operation
where x is an n-element complex vector scattered with stride incx.

5 Arguments

1: n Integer Input
On entry: n, the number of elements in x.
2: con Complex (Kind=nag_wp) Input
On entry: the scalar α.
3: x(*) Complex (Kind=nag_wp) array Input/Output
Note: the dimension of the array x must be at least max(1, 1+(n-1) ×incx ) .
On entry: if |incx|1, intermediate elements of x may contain values and will not be referenced; the other elements will be overwritten and need not be set.
On exit: the elements xi of the vector x will be stored in x(1+(i-1)×incx), for i=1,2,,n.
Intermediate elements of x are unchanged.
4: incx Integer Input
On entry: the increment in the subscripts of x between successive elements of x.
Constraint: incx>0.
