NAME

       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 (integerN, complex*16, dimension( * )CX,
       integerINCX)
       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.
