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.
