Function/Subroutine Documentation

subroutine dla_wwaddw (integerN, 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
 arithmetics, 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.
