Description: matlab程序，对一个混沌系统进行仿真。
lyapunov.m是计算的主程序；qi_hyper.m是一个例子（qi系统），利用qi_hyper_lyap.m计算所有李氏指数，利用qi_hyper_lyapDim.m计算分形维数。其他系统稍作改正就可使用。经验证程序比其他计算李氏指数的更为有效精确。-matlab program for a simulation of chaotic systems. lyapunov.m are calculated in the main program qi_hyper.m are a case in point (qi system), the use of all qi_hyper_lyap.m calculated Lyapunov exponent, using qi_hyper_lyapDim.m calculated the fractal dimension. Other systems can be used to make some corrections. Experience in the certification process than any other computing Lyapunov exponent of the more effective precision. Platform: |

Description: 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: -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.
