以下是Logistic映射自相关的MATLAB代码:
```matlab
function x = logistic_map(r, x0, n)
% r: 控制参数
% x0: 初始值
% n: 迭代次数
x = zeros(1, n);
x(1) = x0;
for i = 2:n
x(i) = r * x(i-1) * (1 - x(i-1));
end
end
```
这段代码定义了一个函数`logistic_map`,它接收三个输入参数:控制参数`r`、初始值`x0`和迭代次数`n`。函数通过迭代计算生成了一个指定长度的Logistic映射序列,并返回结果。
你可以调用这个函数来生成Logistic映射序列,示例如下:
```matlab
r = 3.9; % 控制参数
x0 = 0.4; % 初始值
n = 100; % 迭代次数
x = logistic_map(r, x0, n);
plot(x);
```
这段代码中,我们定义了控制参数`r`为3.9,初始值`x0`为0.4,迭代次数`n`为100。然后调用`logistic_map`函数生成Logistic映射序列,并使用`plot`函数将序列可视化。
请注意,这只是一种生成Logistic映射序列的方法,其中控制参数和初始值可以根据需求进行调整。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
