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

- 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.
