Function/Subroutine Documentation

  subroutine zlartv (integer n, complex*16, dimension( * ) x, integer incx, complex*16, dimension( * ) y, integer incy, double precision, dimension( * ) c, complex*16, dimension( * ) s, integer incc)

ZLARTV applies a vector of plane rotations with real cosines and complex sines to the elements of a pair of vectors.

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) )
    !>
