scsum1 (3) - Linux Man Pages
REAL function scsum1 (integerN, complex, dimension( * )CX, integerINCX)
SCSUM1 forms the 1-norm of the complex vector using the true absolute value.
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.
N is INTEGER The number of elements in the vector CX.
CX is COMPLEX array, dimension (N) The vector whose elements will be summed.
INCX is INTEGER The spacing between successive values of CX. INCX > 0.
