Intel® C++ Compiler 16.0 User and Reference Guide
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 svml library are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.
