Expand description

Multiply packed complex numbers in a and b, accumulate to the corresponding complex numbers in c, and store the results in 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].
