NAME

DLARTV - applie a vector of real plane rotations to elements of the real vectors x and y

SYNOPSIS

SUBROUTINE DLARTV(

N, X, INCX, Y, INCY, C, S, INCC )

INTEGER

INCC, INCX, INCY, N

DOUBLE

PRECISION C( * ), S( * ), X( * ), Y( * )

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) )

ARGUMENTS

N (input) INTEGER

The number of plane rotations to be applied.

X (input/output) DOUBLE PRECISION array,

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

INCX (input) INTEGER

The increment between elements of X. INCX > 0.

Y (input/output) DOUBLE PRECISION array,

dimension (1+(N-1)*INCY) The vector y.

INCY (input) INTEGER

The increment between elements of Y. INCY > 0.

C (input) DOUBLE PRECISION array, dimension (1+(N-1)*INCC)

The cosines of the plane rotations.

S (input) DOUBLE PRECISION array, dimension (1+(N-1)*INCC)

The sines of the plane rotations.

INCC (input) INTEGER

The increment between elements of C and S. INCC > 0.
