# sla\_wwaddw(3lapack)

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

## NAME

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

## SYNOPSIS

- SUBROUTINE SLA\_WWADDW(

  N, X, Y, W )

- IMPLICIT

  NONE

- INTEGER

  N

- REAL

  X( \* ), Y( \* ), W( \* )

## PURPOSE

   SLA\_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
