Function/Subroutine Documentation

subroutine dla_wwaddw (integer n, double precision, dimension( * ) x, double precision, dimension( * ) y, double precision, dimension( * ) w)

DLA_WWADDW adds a vector into a doubled-single vector.

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
!>    arithmetic, but not for decimal.
!>

Parameters

N

!>          N is INTEGER
!>            The length of vectors X, Y, and W.
!>

X

!>          X is DOUBLE PRECISION array, dimension (N)
!>            The first part of the doubled-single accumulation vector.
!>

Y

!>          Y is DOUBLE PRECISION array, dimension (N)
!>            The second part of the doubled-single accumulation vector.
!>

W

!>          W is DOUBLE PRECISION array, dimension (N)
!>            The vector to be added.
