Duffing Attractor Written by Paul Bourke — The solution to the Duffing equations is often used as an example of a classic chaotic system. The Duffing system of differential equations is: =========== dx / dt = y dy / dt = x - x3 - a y + b cos(w t) =================================== where typically, a = 0.25, b = 0.3, w = 1 The following shows a "typical" segment of (x,y) values.

• A a value (default 0.25), optional
  type: float
  

• B b value (default 0.3), optional
