Many physical systems with complex spatiotemporal behavior give rise to structures with fractal geometries in phase space or real space1,2. The paradigm of such a fractal structure in phase space is the strange attractor appearing in the chaotic motion of a dissipative system. The structure of a strange attractor is statistically self-similar. Several techniques of evaluating the fractal dimension have been widely used3.
