vbesyn - Vector Bessel Function Yn(x)

10.6 vbesyn - Vector Bessel Function $Yn(x)$

#include <mvec.h> 
 
void vbesyn (int n, double *restrict y, int incy, int k, const double *restrict x, int incx); 
void vbesynf(int n, float *restrict y, int incy, int k, const float *restrict x, int incx); 
 
 
#include <mvec64.h> 
 
void vbesyn_64 (long n, double *restrict y, long incy, long k, const double *restrict x, long incx); 
void vbesynf_64(long n, float *restrict y, long incy, long k, const float *restrict x, long incx);

Given an input vector $x$ , an order $k$ and a result vector $y$ , this function computes:

y= Yk(x)

10.6.1 Parameters

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