SYNOPSIS
Functions/Subroutines
subroutine sla_wwaddw (N, X, Y, W)
SLA_WWADDW
Function/Subroutine Documentation
subroutine sla_wwaddw (integerN, real, dimension( * )X, real, dimension( * )Y, real, dimension( * )W)
SLA_WWADDW
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.
Parameters:
N
N is INTEGER
The length of vectors X, Y, and W.
X
X is REAL array, dimension (N)
The first part of the doubled-single accumulation vector.
Y
Y is REAL array, dimension (N)
The second part of the doubled-single accumulation vector.
W
W is REAL array, dimension (N)
The vector to be added.

SYNOPSIS
Functions/Subroutines
subroutine slar2v (N, X, Y, Z, INCX, C, S, INCC)
SLAR2V
Function/Subroutine Documentation
subroutine slar2v (integerN, real, dimension( * )X, real, dimension( * )Y, real, dimension( * )Z, integerINCX, real, dimension( * )C, real,
dimension( * )S, integerINCC)
SLAR2V
Purpose:
SLAR2V applies a vector of real plane rotations from both sides to
a sequence of 2-by-2 real symmetric matrices, defined by the elements
of the vectors x, y and z. For i = 1,2,...,n
( x(i) z(i) ) := ( c(i) s(i) ) ( x(i) z(i) ) ( c(i) -s(i) )
( z(i) y(i) ) ( -s(i) c(i) ) ( z(i) y(i) ) ( s(i) c(i) )
Parameters:
N
N is INTEGER
The number of plane rotations to be applied.
X
X is REAL array,
dimension (1+(N-1)*INCX)
The vector x.
Y
Y is REAL array,
dimension (1+(N-1)*INCX)
The vector y.
Z
Z is REAL array,
dimension (1+(N-1)*INCX)
The vector z.
INCX
INCX is INTEGER
The increment between elements of X, Y and Z. INCX > 0.
C
C is REAL array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.
S
S is REAL array, dimension (1+(N-1)*INCC)
The sines of the plane rotations.
INCC
INCC is INTEGER
The increment between elements of C and S. INCC > 0.
