3.318. __nv_yn

Prototype:

double @__nv_yn(i32 %n, double %x) 

Description:

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.
  • __nv_yn(n, x) returns NaN for n < 0.

  • __nv_yn(n, 0) returns .

  • __nv_yn(n, x) returns NaN for x < 0.

  • __nv_yn(n, + ) returns +0.

  • __nv_yn(n, NaN) returns NaN.
