Expand description

Multiply packed complex numbers in a and 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]`.
