Calculates inverse error function. Vector variant of erfinv(x) function for a 128-bit/256-bit vector argument of float64 values.
extern __m128d _mm_erfinv_pd(__m128d v1); |
extern __m256d _mm256_erfinv_pd(__m256d v1); |
v1 |
float64 vector used for the operation |
Calculates the inverse error function of v1 elements, which is defined as:
1 / erf(x)
128-bit/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.
