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, and store the results in dst using writemask k (the element is copied from c when the 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].
