Calculates inverse error function. Vector variant of erfinv(x) function for a 128-bit/256-bit vector argument of float32 values.

Syntax

extern __m128 _mm_erfinv_ps(__m128 v1);
extern __m256 _mm256_erfinv_ps(__m256 v1);
Arguments
v1
vector with float32 values
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
