NAME
     DLARGV - generate a vector of real plane rotations, determined by
     elements of the real vectors x and y

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

         INTEGER        INCC, INCX, INCY, N

         DOUBLE         PRECISION C( * ), X( * ), Y( * )

PURPOSE
     DLARGV generates a vector of real plane rotations, determined by elements
     of the real vectors x and y. For i = 1,2,...,n

        (  c(i)  s(i) ) ( x(i) ) = ( a(i) )
        ( -s(i)  c(i) ) ( y(i) ) = (   0  )


ARGUMENTS
     N       (input) INTEGER
             The number of plane rotations to be generated.

     X       (input/output) DOUBLE PRECISION array,
             dimension (1+(N-1)*INCX) On entry, the vector x.  On exit, x(i)
             is overwritten by a(i), for i = 1,...,n.

     INCX    (input) INTEGER
             The increment between elements of X. INCX > 0.

     Y       (input/output) DOUBLE PRECISION array,
             dimension (1+(N-1)*INCY) On entry, the vector y.  On exit, the
             sines of the plane rotations.

     INCY    (input) INTEGER
             The increment between elements of Y. INCY > 0.

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

     INCC    (input) INTEGER
             The increment between elements of C. INCC > 0.
