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.
