DZSUM1(3)      LAPACK routine of NEC Numeric Library Collection      DZSUM1(3)



NAME
       DZSUM1

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



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.




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

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

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