_mm256_erfinv_pd

Calculates inverse error function. Vector variant of erfinv(x) function for a 128-bit/256-bit vector argument of float64 values.

Syntax

extern __m128d _mm_erfinv_pd(__m128d v1);
extern __m256d _mm256_erfinv_pd(__m256d v1);
Arguments
v1
float64 vector used for the operation
Description
Calculates the inverse error function of
v1
elements, which is defined as:
1 / erf(x)
Returns
128-bit/256-bit vector with the result of the operation.
Many routines in the
svml
library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
