Purpose:
Multiply packed double-precision (64-bit) floating-point elements in a and b, and store the results in output.
Result:
A 128-bit vector of 2 x 64-bit double-precision floating-point that hold the result of the multiplication.
Example:
#include <emmintrin.h>
#include <stdio.h>
int main() {
__m128d a = _mm_setr_pd(1.0, 2.0);
__m128d b = _mm_setr_pd(3.0, 4.0);
__m128d result = _mm_mul_pd(a, b);
double* res = (double*)&result;
for(int i = 0; i < 2; i++) {
printf("%f ", res[i]);
}
return 0;
