3.84. __nv_erfinv

Prototype:

double @__nv_erfinv(double %x) 

Description:

Calculate the inverse error function of the input argument y, for y in the interval [-1, 1]. The inverse error function finds the value x that satisfies the equation y = erf(x), for 1 y 1 , and x .

Returns:

  • __nv_erfinv(1) returns + .

  • __nv_erfinv(-1) returns .

Note:

For accuracy information for this function see the CUDA C Programming Guide, Appendix C, Table C-2.

Library Availability:

Compute 2.0: Yes

Compute 3.0: Yes

Compute 3.5: Yes
