 NAME
      SLARGV - generate a vector of real plane rotations, deter-
      mined by elements of the real vectors x and y

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

          INTEGER        INCC, INCX, INCY, N

          REAL           C( * ), X( * ), Y( * )

 PURPOSE
      SLARGV generates a vector of real plane rotations, deter-
      mined 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) REAL 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) REAL 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) REAL array, dimension (1+(N-1)*INCC)
              The cosines of the plane rotations.

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