Intrinsics for FP Pack and Unpack Operations
The prototypes for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) intrinsics are located in the zmmintrin.h header file.
To use these intrinsics, include the immintrin.h file as follows:
#include <immintrin.h>

_mm512_unpackhi_pd
extern __m512d __cdecl _mm512_unpackhi_pd(__m512d a, __m512d b);
Unpacks and interleaves float64 elements from the high half of each 128-bit lane in a and b, and stores the result.
_mm512_mask_unpackhi_pd
extern __m512d __cdecl _mm512_mask_unpackhi_pd(__m512d src, __mmask8 k, __m512d a, __m512d b);
Unpacks and interleaves float64 elements from the high half of each 128-bit lane in a and b, and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).
_mm512_maskz_unpackhi_pd
extern __m512d __cdecl _mm512_maskz_unpackhi_pd(__mmask8 k, __m512d a, __m512d b);
Unpacks and interleaves float64 elements from the high half of each 128-bit lane in a and b, and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
_mm512_unpackhi_ps
extern __m512 __cdecl _mm512_unpackhi_ps(__m512 a, __m512 b);
Unpacks and interleaves float32 elements from the high half of each 128-bit lane in a and b, and stores the result.

Unpacks and interleaves float32 elements from the high half of each 128-bit lane in a and b, and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).
_mm512_maskz_unpackhi_ps
extern __m512 __cdecl _mm512_maskz_unpackhi_ps(__mmask16 k, __m512 a, __m512 b);
Unpacks and interleaves float32 elements from the high half of each 128-bit lane in a and b, and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
_mm512_unpacklo_pd
extern __m512d __cdecl _mm512_unpacklo_pd(__m512d a, __m512d b);
