__device__ double yn ( int  n,
double  x 
)

Calculate the value of the Bessel function of the second kind of order n for the input argument x, $Y_n(x)$.

Returns:
Returns the value of the Bessel function of the second kind of order n.
  • yn(n, x) returns NaN for n < 0.
  • yn(n, 0) returns $-\infty$.
  • yn(n, x) returns NaN for x < 0.
  • yn(n, $+\infty$) returns +0.
  • yn(n, NaN) returns NaN.
