Expand description

Multiply the lower complex numbers in a and b, accumulate to the lower complex number in c, and store the result in the lower elements of dst using writemask k (elements are copied from a when mask bit 0 is not set), and copy the upper 6 packed elements from a to the upper elements of 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]`.
