Calculates inverse error function. Vector variant of erfinv(x) function for a 128-bit/256-bit vector argument of float32 values.
extern __m128 _mm_erfinv_ps(__m128 v1); |
extern __m256 _mm256_erfinv_ps(__m256 v1); |
v1 |
vector with float32 values |
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 Short Vector Math Library (SVML) are more optimized for Intel® microprocessors than for non-Intel microprocessors.
