🔬 This is a nightly-only experimental API. (stdsimd #48556)
Available on x86-64 and target feature avx512f,avx512vl only.
Expand description

Scale the packed double-precision (64-bit) floating-point elements in a using values from b, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
