#127213)Available on (x86 or x86-64) and target feature
avx512fp16
and x86-64 only.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 zeromask k (elements are zeroed out 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]
.
