NAME
       SRC/dzsum1.f

SYNOPSIS
   Functions/Subroutines
       double precision function dzsum1 (n, cx, incx)
           DZSUM1 forms the 1-norm of the complex vector using the true
           absolute value.

Function/Subroutine Documentation
   double precision function dzsum1 (integer n, complex*16, dimension( * ) cx,
       integer incx)
       DZSUM1 forms the 1-norm of the complex vector using the true absolute
       value.

       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.
           !>

       Parameters
           N

           !>          N is INTEGER
           !>          The number of elements in the vector CX.
           !>

           CX

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

           INCX

           !>          INCX is INTEGER
           !>          The spacing between successive values of CX.  INCX > 0.
           !>
