赋个初值看看：

 

 我们使用雅克比矩阵计算lyapunov exponent图谱看看：

 

 

matlab代码如下：

clear;
%% ===========初始化输入==============
yinit = [0.1,0.1,0.1];
orthmatrix = [1 0 0;
    0 1 0;
    0 0 1];

y = zeros(12,1);
y(1:3) = yinit;
y(4:12) = orthmatrix;

mod = zeros(3,1);
lp = zeros(3,1);

%% ============迭代控制==============
