ZLARTV(3)      LAPACK routine of NEC Numeric Library Collection      ZLARTV(3)



NAME
       ZLARTV

SYNOPSIS
       SUBROUTINE ZLARTV (N, X, INCX, Y, INCY, C, S, INCC)



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) )
