5  Arguments

1:     n – IntegerInput

On entry: $n$, the number of elements in $x$.

Constraint: $\mathbf{n}\ge 0$.

2:     alpha – IntegerInput

On entry: the scalar $\alpha$.

3:     x[$\mathit{dim}$] – IntegerOutput

Note: the dimension, dim, of the array x must be at least $\max \left(1,1+\left(\mathbf{n}-1\right)\left|\mathbf{incx}\right|\right)$.

On exit: the scalar $\alpha$ is scattered with a stride of incx in x. Intermediate elements of x are unchanged.

4:     incx – IntegerInput

On entry: the increment in the subscripts of x between successive elements of $x$.

Constraint: $\mathbf{incx}\ne 0$.

5:     fail – NagError *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 $〈\mathit{\text{value}}〉$ had an illegal value.

NE_INT

On entry, $\mathbf{incx}=〈\mathit{\text{value}}〉$.
Constraint: $\mathbf{incx}\ne 0$.

On entry, $\mathbf{n}=〈\mathit{\text{value}}〉$.
Constraint: $\mathbf{n}\ge 0$.
