   Functions/Subroutines
       subroutine dlartv (N, X, INCX, Y, INCY, C, S, INCC)

Function/Subroutine Documentation

   subroutine dlartv (integer N, double precision, dimension( * ) X, integer INCX, double
       precision, dimension( * ) Y, integer INCY, double precision, dimension( * ) C, double
       precision, dimension( * ) S, integer INCC)
       DLARTV applies a vector of plane rotations with real cosines and real sines to the
       elements of a pair of vectors.

       Purpose:

            DLARTV 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) )

       Parameters:
           N

                     N is INTEGER
                     The number of plane rotations to be applied.

           X

                     X is DOUBLE PRECISION array,
                                    dimension (1+(N-1)*INCX)
                     The vector x.

           INCX

                     INCX is INTEGER
                     The increment between elements of X. INCX > 0.

           Y

                     Y is DOUBLE PRECISION array,
                                    dimension (1+(N-1)*INCY)
                     The vector y.

           INCY

                     INCY is INTEGER
                     The increment between elements of Y. INCY > 0.

           C

                     C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
                     The cosines of the plane rotations.

           S

                     S is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
                     The sines of the plane rotations.

           INCC

                     INCC is INTEGER
                     The increment between elements of C and S. INCC > 0.
