#127213)Available on (x86 or x86-64) and target feature
avx512fp16,avx512vl
and x86 only.Expand description
Multiply packed complex numbers in a by the complex conjugates of packed complex numbers in b, and
store the results in dst using writemask k (the element is copied from src when corresponding mask bit is not set).
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]
.
