    pub fn _mm512_maskz_fcmul_pch(k: __mmask16, a: __m512h, b: __m512h) -> __m512h

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

Multiply packed complex numbers in a by the complex conjugates of packed complex numbers in b, 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]`.
