Arguments

1:     $\mathbf{n}$ – IntegerInput

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

2:     $\mathbf{con}$ – IntegerInput

On entry: the scalar $\alpha$.

3:     $\mathbf{x}\left(*\right)$ – Integer arrayInput/Output

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

On entry: if $\left|\mathbf{incx}\right|\ne 1$, 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 $x_i$ of the vector $x$ will be stored in $\mathbf{x}\left(1+\left(\mathit{i}-1\right)\times \mathbf{incx}\right)$, for $\mathit{i}=1,2,\dots ,\mathbf{n}$.

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: $\mathbf{incx}>0$.
