_mm_erf_pd, _mm256_erf_pd

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

Syntax

extern __m128d _mm_erf_pd(__m128d v1);

extern __m256d _mm256_erf_pd(__m256d v1);

Arguments

v1

float64 vector used for the operation

Description

Calculates error function of v1 elements, which is defined as:

erf(x) = 2/sqrt(pi)* integral from 0 to x of exp(-t*t) dt

Returns

128-bit or 256-bit vector with the result of the operation.

Many routines in the svml library are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.
