pub unsafe fn _mm_mask_conj_pch(src: __m128h, k: u8, a: __m128h) -> __m128h🔬This is a nightly-only experimental API. (

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].
