🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16
#127213)Available on (x86 or x86-64) and target feature
avx512fp16
and x86 only.Expand description
Multiply the lower complex numbers in a by the complex conjugates of the lower complex numbers in b,
and store the results in dst using zeromask k (the element is zeroed out when mask bit 0 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]
.
