void vmod (int n, double *restrict z, int incz, const double *restrict x, 
           int incx, const double *restrict y, int incy);

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

z =mod(x,y)

8.13.1 Parameters

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