## 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.
