polygon_area — DRIVE `japan` op

• Data kinds: any → scalar

• Call: import fullseye as fs; fs.ledger.polygon_area(poly: 'np.ndarray | Sequence[Sequence[float]]') -> 'float' (to call the implementation directly, import driveplateau; driveplateau.polygon_area(poly: 'np.ndarray | Sequence[Sequence[float]]') -> 'float'; from the registry, opsdrive.get("polygon_area"))

Usage

Signed area of a simple polygon (shoelace formula). Positive for counterclockwise.

Raises:

ValueError: 形が (k,2) でない、k < 3、非有限値。
