# Function core::arch::x86::_mm512_maskz_insertf64x4
[−][src]

    pub unsafe fn _mm512_maskz_insertf64x4(
        k: __mmask8,
        a: __m512d,
        b: __m256d,
        imm8: i32
    ) -> __m512d

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512f` only.

Copy a to tmp, then insert 256 bits (composed of 4 packed double-precision (64-bit) floating-point elements) from b into tmp at the location specified by imm8. Store tmp to dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
