matlab计算李雅普诺夫指数 如何理解和计算Lyapunov exponent spectrum? 1、这是我听到最接近人话的描述。 混沌运动的基本特点是运动对初始条件极为敏感,两个极为靠近的初始值所产生的轨迹,随着时间推移将按照指数方式分离。李娜诺普指数就是描述这一现象的量。 2、 结论: --- --- 计算方法来了: 求解指数的这一...
Since expansion range can only be specified using whole numbers, round-offKminandKmaxto the nearest integer. Find the largest Lyapunov exponent of the Lorenz attractor using the new expansion range value. Kmin = 21; Kmax = 161; lyapExp = lyapunovExponent(xdata,fs,lag,dim,'ExpansionRange',[Km...

The function i'm interested in has been submitted by the COMMUNITY: MathWorks FileExchange website for community implementations of Lyapunov Exponent calculations. https://www.mathworks.com/matlabcentral/fileexchange/4628-calculation-lyapunov-exponents-for-ode However, this one apparently works with ODE...
This Matlab software is based on the ode87. Therefore, the local error normally expected is O (h9) since the ode87 is an eighth-order accurate integrator. Sign in to download full-size image Fig. 6. Lyapunov spectrum of system (2). The largest positive exponent λ1, which increases the...
