SCSUM1  - take the sum of the absolute values of a complex
       vector and returns a single precision result


SYNOPSIS

       REAL FUNCTION SCSUM1( N, CX, INCX )

           INTEGER   INCX, N

           COMPLEX   CX( * )


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.

ARGUMENTS

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

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

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