Dequan Li Attractor — Li (2008): a three-scroll attractor, the scrolls joined through the z axis. Stiff: its default step is small, and larger steps of dt make the trajectory leave the attractor.
dx/dt = a(y − x) + cxz dy/dt = ex + fy − xz dz/dt = bz + xy − dx²Open Dequan Li in chaosrack →
It opens running, on the model selector, with its own knobs. Rotate it by dragging, zoom with the wheel, and turn the parameters to see what the figure does when the system changes.
