Prototype: 

float @__nv_y1f(float %x)

Description:

Calculate the value of the Bessel function of the second kind of order 1 for the input argument x, Y 1 ( x ) .

Returns:

Returns the value of the Bessel function of the second kind of order 1.

  • __nv_y1f(0) returns − ∞ .

  • __nv_y1f(x) returns NaN for x < 0.

  • __nv_y1f( + ∞ ) returns +0.

  • __nv_y1f(NaN) returns NaN.
