  *  Purpose\n\
  *  =======\n\
  *\n\
  *  DLARGV generates a vector of real plane rotations, determined by\n\
  *  elements of the real vectors x and y. For i = 1,2,...,n\n\
  *\n\
  *     (  c(i)  s(i) ) ( x(i) ) = ( a(i) )\n\
  *     ( -s(i)  c(i) ) ( y(i) ) = (   0  )\n\
  *\n\n\
  *  Arguments\n\
  *  =========\n\
  *\n\
  *  N       (input) INTEGER\n\
  *          The number of plane rotations to be generated.\n\
  *\n\
  *  X       (input/output) DOUBLE PRECISION array,\n\
  *                         dimension (1+(N-1)*INCX)\n\
  *          On entry, the vector x.\n\
  *          On exit, x(i) is overwritten by a(i), for i = 1,...,n.\n\
  *\n\
  *  INCX    (input) INTEGER\n\
  *          The increment between elements of X. INCX > 0.\n\
