🔬This is a nightly-only experimental API. (
stdarch_x86_avx512_f16
#127213)Available on (x86 or x86-64) and target feature
avx512fp16,avx512vl
and x86 only.Expand description
Compute the complex conjugates of complex numbers in a, 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]
,
or the complex conjugate conjugate = vec.fp16[0] - i * vec.fp16[1]
.
