Function/Subroutine Documentation

  subroutine slartv (integer n, real, dimension( * ) x, integer incx, real, dimension( * ) y, integer incy, real, dimension( * ) c, real, dimension( * ) s, integer incc)

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

Purpose:

    !>
    !> SLARTV 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) )
    !>
