NAME
       SRC/scsum1.f

SYNOPSIS
   Functions/Subroutines
       real function scsum1 (n, cx, incx)
           SCSUM1 forms the 1-norm of the complex vector using the true
           absolute value.

Function/Subroutine Documentation
   real function scsum1 (integer n, complex, dimension( * ) cx, integer incx)
       SCSUM1 forms the 1-norm of the complex vector using the true absolute
       value.

       Purpose:


            SCSUM1 takes the sum of the absolute values of a complex
            vector and returns a single precision result.

            Based on SCASUM 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 array, dimension (N)
                     The vector whose elements will be summed.

           INCX

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