# Function core::arch::x86_64::_mm512_mask_permutex2var_ps[−][src]

    pub unsafe fn _mm512_mask_permutex2var_ps(
        a: __m512,
        k: __mmask16,
        idx: __m512i,
        b: __m512
    ) -> __m512

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f` only.

Shuffle single-precision (32-bit) floating-point elements in a and b across lanes using the corresponding selector and index in idx, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
