DZSUM1(l) ) DZSUM1(l)NAME
DZSUM1 - take 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.

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.
