Synopsis
_mm512_mask_atan_pd(__m512d src, __mmask8 k, __m512d a);
Description
Compute the inverse tangent of packed double-precision (64-bit) floating-point elements in "a", and store the results in "dst" expressed in radians using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
i := j*64
IF k[j]
dst[i+63:i] := ATAN(a[i+63:i])
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
