# dla\_wwaddw(3lapack)

DLA\_WWADDW add a vector W into a doubled-single vector (X, Y)

## NAME

DLA\_WWADDW - 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, Y   (input/output) DOUBLE PRECISION array, length N The doubled-single accumulation vector.

- W (input) DOUBLE PRECISION array, length N

  The vector to be added.
