_mm_erfinv_pd, _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.

NOTE:

Many routines in the Short Vector Math Library (SVML) are more optimized for Intel® microprocessors than for non-Intel microprocessors.
