:fortran_help: "      DOUBLE PRECISION FUNCTION DZSUM1( N, CX, INCX )\n\n\
  *  Purpose\n\
  *  =======\n\
  *\n\
  *  DZSUM1 takes the sum of the absolute values of a complex\n\
  *  vector and returns a double precision result.\n\
  *\n\
  *  Based on DZASUM from the Level 1 BLAS.\n\
  *  The change is to use the 'genuine' absolute value.\n\
  *\n\
  *  Contributed by Nick Higham for use with ZLACON.\n\
  *\n\n\
  *  Arguments\n\
  *  =========\n\
  *\n\
  *  N       (input) INTEGER\n\
  *          The number of elements in the vector CX.\n\
  *\n\
  *  CX      (input) COMPLEX*16 array, dimension (N)\n\
  *          The vector whose elements will be summed.\n\
  *\n\
  *  INCX    (input) INTEGER\n\
  *          The spacing between successive values of CX.  INCX > 0.\n\
