Intrinsics for FP Expand and Load 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:

_mm512_expand_pd
extern __m512d __cdecl _mm512_expand_pd(__m512d a);
Loads contiguous active float64 elements from a (those with their respective bit set in mask k), and stores the result.
_mm512_mask_expand_pd
extern __m512d __cdecl _mm512_mask_expand_pd(__m512d src, __mmask8 k, __m512d a);
Loads contiguous active float64 elements from a (those with their respective bit set in mask k), and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).
_mm512_maskz_expand_pd
extern __m512d __cdecl _mm512_maskz_expand_pd(__mmask8 k, __m512d a);
Loads contiguous active float64 elements from a (those with their respective bit set in mask k), and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
_mm512_expand_ps
extern __m512 __cdecl _mm512_expand_ps(__m512 a);
Loads contiguous active float32 elements from a (those with their respective bit set in mask k), and stores the result.
_mm512_mask_expand_ps
extern __m512 __cdecl _mm512_mask_expand_ps(__m512 src, __mmask16 k, __m512 a);
Loads contiguous active float32 elements from a (those with their respective bit set in mask k), and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).
_mm512_maskz_expand_ps
extern __m512 __cdecl _mm512_maskz_expand_ps(__mmask16 k, __m512 a);
Loads contiguous active float32 elements from a (those with their respective bit set in mask k), and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
_mm512_mask_expandloadu_pd
extern __m512d __cdecl _mm512_mask_expandloadu_pd(__m512d src, __mmask8 k, void * mem_addr);
Loads contiguous active float64 elements from unaligned memory at mem_addr (those with their respective bit set in mask k), and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).
_mm512_maskz_expandloadu_pd
extern __m512d __cdecl _mm512_maskz_expandloadu_pd(__mmask8 k, void * mem_addr);
Loads contiguous active float64 elements from unaligned memory at mem_addr (those with their respective bit set in mask k), and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
_mm512_mask_expandloadu_ps
extern __m512 __cdecl _mm512_mask_expandloadu_ps(__m512 src, __mmask16 k, void * mem_addr);
Loads contiguous active float32 elements from unaligned memory at mem_addr (those with their respective bit set in mask k), and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).
_mm512_maskz_expandloadu_ps
extern __m512 __cdecl _mm512_maskz_expandloadu_ps(__mmask16 k, void * mem_addr);
