Purpose:
Multiply packed double-precision (64-bit) floating-point elements in "a" and "b", and store the results in "dst".
Result:
__m512d
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512d a = _mm512_set_pd(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0);
__m512d b = _mm512_set_pd(2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0);
__m512d r = _mm512_mul_pd(a, b);
double* res = (double*)&r;
for (int i = 0; i < 8; ++i)
printf("%f ", res[i]);
return 0;
}Prototypes
