1: $\mathbf{n}$ – Integer Input

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

2: $\mathbf{x}\left(*\right)$ – Complex (Kind=nag_wp) array Input

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

On entry: the $n$-element vector $x$. $x_{\mathit{i}}$ must be stored in $\mathbf{x}\left(1+(\mathit{i}-1)\times \mathbf{incx}\right)$, for $\mathit{i}=1,2,\dots ,\mathbf{n}$.

Intermediate elements of x are not referenced.

3: $\mathbf{incx}$ – Integer Input

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

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