**NAME**

LAPACK-3 - DLA_WWADDW add a vector W into a doubled-single vector (X, Y)

**SYNOPSIS**

SUBROUTINE DLA_WWADDW( N, X, Y, W ) IMPLICIT NONE INTEGER N DOUBLE PRECISION X( * ), Y( * ), W( * )

**PURPOSE**

DLA_WWADDW adds a vector W into a doubled-single vector (X, Y). This works for all extant IBM's hex and binary floating point arithmetics, but not for decimal.

**ARGUMENTS**

N (input) INTEGER The length of vectors X, Y, and W. X (input/output) DOUBLE PRECISION array, dimension (N) The first part of the doubled-single accumulation vector. Y (input/output) DOUBLE PRECISION array, dimension (N) The second part of the doubled-single accumulation vector. W (input) DOUBLE PRECISION array, dimension (N) The vector to be added.
