vpows - Vector power scalar exponentxy

8.12 vpows - Vector power scalar exponent $xy$

subroutine vpows (n, z, incz, x, incx, y); 
subroutine vpowsf(n, z, incz, x, incx, y); 
 
subroutine vpows_64 (n, z, incz, x, incx, y); 
subroutine vpowsf_64(n, z, incz, x, incx, y);

Given an input vectors $x$ and a scalar value $y$ as well as a result vector $z$ , this function computes:

z= xy

8.12.1 Parameters

N - INTEGER: ENTRY: Number of elements of $x$ and $y$ .
CONSTRAINT: $n ≥1$ .
z - ARRAY OF REAL: EXIT: Result vector $z$ .
CONSTRAINT: Must contain $n× incz$ elements.
CONSTRAINT: Must not overlap with array $x$ .
INCZ - INTEGER: ENTRY: Stride for the vector $z$ .
CONSTRAINT: $incz̸= 0$ .
BEHAVIOR: A negative stride will traverse the array in reverse.
X - ARRAY OF REAL: ENTRY: Input vector $x$ .
CONSTRAINT: Must contain $n× incx$ elements.
CONSTRAINT: Must not overlap with array $z$ .
INCX - INTEGER: ENTRY: Stride for the vector $x$ .
CONSTRAINT: $incx̸= 0$ .
BEHAVIOR: A negative stride will traverse the array in reverse.
Y - REAL: ENTRY: Exponentiation value $y$ .
