NAME
       BLAS/SRC/dzasum.f

SYNOPSIS
   Functions/Subroutines
       double precision function dzasum (n, zx, incx)
           DZASUM

Function/Subroutine Documentation
   double precision function dzasum (integer n, complex*16, dimension(*) zx,
       integer incx)
       DZASUM

       Purpose:


           !>
           !>    DZASUM takes the sum of the (|Re(.)| + |Im(.)|)'s of a complex vector and
           !>    returns a double precision result.
           !>

       Parameters
           N

           !>          N is INTEGER
           !>         number of elements in input vector(s)
           !>

           ZX

           !>          ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
           !>

           INCX

           !>          INCX is INTEGER
           !>         storage spacing between elements of ZX
           !>
