Detailed Description

Function Documentation

subroutine cla_wwaddw (integer n, complex, dimension( * ) x, complex, dimension( * ) y, complex, dimension( * ) w)

CLA_WWADDW adds a vector into a doubled-single vector.

Purpose:



    CLA_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 COMPLEX array, dimension (N)


            The first part of the doubled-single accumulation vector.

Y



          Y is COMPLEX array, dimension (N)


            The second part of the doubled-single accumulation vector.

W



          W is COMPLEX array, dimension (N)


            The vector to be added.
