avx512fp16 and x86-64 only.Expand description
Multiply packed complex numbers in a by the complex conjugates of packed complex numbers in b, accumulate
to the corresponding complex numbers in c using zeromask k (the element is zeroed out when the corresponding
mask bit is not set), and store the results in dst. Each complex number is composed of two adjacent half-precision
(16-bit) floating-point elements, which defines the complex number complex = vec.fp16[0] + i * vec.fp16[1, or the complex
conjugate conjugate = vec.fp16[0] - i * vec.fp16[1].
Rounding is done according to the rounding parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT|_MM_FROUND_NO_EXC: round to nearest and suppress exceptions_MM_FROUND_TO_NEG_INF|_MM_FROUND_NO_EXC: round down and suppress exceptions_MM_FROUND_TO_POS_INF|_MM_FROUND_NO_EXC: round up and suppress exceptions_MM_FROUND_TO_ZERO|_MM_FROUND_NO_EXC: truncate and suppress exceptions_MM_FROUND_CUR_DIRECTION: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
