Function/Subroutine Documentation
subroutine dlartv (integerN, double precision, dimension( * )X, integerINCX, double precision,
dimension( * )Y, integerINCY, double precision, dimension( * )C, double precision,
dimension( * )S, integerINCC)
DLARTV applies a vector of plane rotations with real cosines and real sines to the
elements of a pair of vectors.
Purpose:
DLARTV applies a vector of real plane rotations to elements of the
real vectors x and y. For i = 1,2,...,n
( x(i) ) := ( c(i) s(i) ) ( x(i) )
( y(i) ) ( s(i) c(i) ) ( y(i) )
Parameters:
N
N is INTEGER
The number of plane rotations to be applied.
X
X is DOUBLE PRECISION array,
dimension (1+(N1)*INCX)
The vector x.
INCX
INCX is INTEGER
The increment between elements of X. INCX > 0.
Y
Y is DOUBLE PRECISION array,
dimension (1+(N1)*INCY)
The vector y.
INCY
INCY is INTEGER
The increment between elements of Y. INCY > 0.
C
C is DOUBLE PRECISION array, dimension (1+(N1)*INCC)
The cosines of the plane rotations.
S
S is DOUBLE PRECISION array, dimension (1+(N1)*INCC)
The sines of the plane rotations.
INCC
INCC is INTEGER
The increment between elements of C and S. INCC > 0.
