Purpose:
Compute the square root of packed double-precision (64-bit) floating-point elements in a, and store the results in output.
Result:
__m256d
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m256d a = _mm256_set_pd(64.0, 49.0, 36.0, 25.0);
__m256d result = _mm256_sqrt_pd(a);
double res[4];
_mm256_storeu_pd(res, result);
printf("%lf %lf %lf %lf\n", res[0], res[1], res[2], res[3]);
return 0;
