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+(N-1)*INCX)
The vector x.

INCX


INCX is INTEGER
The increment between elements of X. INCX > 0.

Y


Y is DOUBLE PRECISION array,
dimension (1+(N-1)*INCY)
The vector y.

INCY


INCY is INTEGER
The increment between elements of Y. INCY > 0.

C


C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.

S


S is DOUBLE PRECISION 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.
