Arguments

1:    $\mathbf{n}$ – IntegerInput

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

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

2:    $\mathbf{alpha}$ – ComplexInput

On entry: the scalar $\alpha$.

3:    $\mathbf{x}\left[\mathit{dim}\right]$ – ComplexOutput

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 $\alpha$ scattered with a stride of incx. Intermediate elements of x are unchanged.

4:    $\mathbf{incx}$ – IntegerInput

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

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

5:    $\mathbf{fail}$ – NagError *Input/Output

The NAG error argument (see Section 3.7 in How to Use the NAG Library and its Documentation).

Dynamic memory allocation failed.
See Section 2.3.1.2 in How to Use the NAG Library and its Documentation for further information.

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