Sample software that implements this procedure while searching for chaotic solutions in general 2-D quadratic maps is available in (DOS) BASIC source and executable code. Sample software that calculates the Lyapunov exponent (-0.5 to 0.5) for the Hénon Map Xn+1 = 1 - CXn2 + BXn-1 for B = 0.3 and 0 < C < 2 is also available in (DOS) BASIC source and executable code. Output from that program is shown below:
