NAME

ZLARTV - applies a vector of complex plane rotations with real cosines to elements of the complex vectors x and y

SYNOPSIS

SUBROUTINE ZLARTV(: N, X, INCX, Y, INCY, C, S, INCC )
: INTEGER INCC, INCX, INCY, N
: DOUBLE PRECISION C( * )
: COMPLEX*16 S( * ), X( * ), Y( * )

PURPOSE

ZLARTV applies a vector of complex plane rotations with real cosines to elements of the complex vectors x and y. For i = 1,2,...,n
( x(i) ) := ( c(i) s(i) ) ( x(i) )

( y(i) ) ( -conjg(s(i)) c(i) ) ( y(i) )

ARGUMENTS

N (input) INTEGER: The number of plane rotations to be applied.
X (input/output) COMPLEX*16 array, dimension (1+(N-1)*INCX): The vector x.
INCX (input) INTEGER: The increment between elements of X. INCX > 0.
Y (input/output) COMPLEX*16 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) COMPLEX*16 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.
