DZSUM1(1)	    LAPACK auxiliary routine (version 3.2)	     DZSUM1(1)

NAME
       DZSUM1  -  takes the sum of the absolute values of a complex vector and
       returns a double precision result

SYNOPSIS
       DOUBLE PRECISION FUNCTION DZSUM1( N, CX, INCX )

	   INTEGER	INCX, N

	   COMPLEX*16	CX( * )

PURPOSE
       DZSUM1 takes the sum of the absolute values of  a  complex  vector  and
       returns	a  double  precision result.  Based on DZASUM from the Level 1
       BLAS.
       The change is to use the 'genuine' absolute value.
       Contributed by Nick Higham for use with ZLACON.

ARGUMENTS
       N       (input) INTEGER
	       The number of elements in the vector CX.

       CX      (input) COMPLEX*16 array, dimension (N)
	       The vector whose elements will be summed.

       INCX    (input) INTEGER
	       The spacing between successive values of CX.  INCX > 0.
