**NAME**

LAPACK-3 - takes 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. Contributed by Nick Higham for use with CLACON.

**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. LAPACK auxiliary routine (version 3.2) April 2011 SCSUM1(3lapack)
