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 zeromask k (the element is zeroed out 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].
