1  Purpose

nag_iload (f16dbc) broadcasts a scalar into an integer vector.

2  Specification

#include <nag.h>
#include <nagf16.h>
void  nag_iload (Integer n, Integer alpha, Integer x[], Integer incx, NagError *fail)

3  Description

nag_iload (f16dbc) performs the operation
x α,α,,αT ,
where x is an n-element integer vector and α is an integer scalar.

5  Arguments

1:     nIntegerInput
On entry: n, the number of elements in x.
Constraint: n0.
2:     alphaIntegerInput
On entry: the scalar α.
3:     x[dim]IntegerOutput
Note: the dimension, dim, of the array x must be at least max1,1+n-1incx.
On exit: the scalar α is scattered with a stride of incx in x. Intermediate elements of x are unchanged.
4:     incxIntegerInput
On entry: the increment in the subscripts of x between successive elements of x.
Constraint: incx0.
5:     failNagError *Input/Output
The NAG error argument (see Section 3.6 in the Essential Introduction).

6  Error Indicators and Warnings

NE_BAD_PARAM
On entry, argument value had an illegal value.
NE_INT
On entry, incx=value.
Constraint: incx0.
On entry, n=value.
Constraint: n0.

7  Accuracy

The BLAS standard requires accurate implementations which avoid unnecessary over/underflow (see Section 2.7 of Basic Linear Algebra Subprograms Technical (BLAST) Forum (2001)).

8  Parallelism and Performance

Not applicable.

9  Further Comments

None.

10  Example
