    pub fn _mm256_mask_conj_pch(src: __m256h, k: __mmask8, a: __m256h) -> __m256h

Available on x86-64 and target feature `avx512fp16` and target feature `avx512vl` only.
Expand description

Compute the complex conjugates of complex numbers in a, and store the results in dst using writemask k (the element is copied from src 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]`.
