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.
