Synopsis
_mm512_mask_hypot_pd(__m512d src, __mmask8 k, __m512d a, __m512d b);
Description
Compute the length of the hypotenous of a right triangle, with the lengths of the other two sides of the triangle stored as packed double-precision (64-bit) floating-point elements in "a" and "b", and store the results in "dst" 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] := SQRT(POW(a[i+63:i], 2.0) + POW(b[i+63:i], 2.0))
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
