马尔科夫预测
3星 · 编辑精心推荐
马尔科夫模型是一种用于建模系统状态和状态转移的工具,通过模拟不同的状态转移,可以预测系统在给定条件下的未来状态。在MATLAB中,可以使用markovchain函数来创建马尔科夫链对象并模拟状态转移。下面是一个完整的MATLAB代码示例:
```matlab
states = ["T", "W", "D", "L"];
transition_matrix = [0.4 0.3 0.2 0.1; 0.1 0.6 0.2 0.1; 0.2 0.3 0.4 0.1; 0.1 0.1 0.2 0.6];
mc = markovchain(transition_matrix, states);
num_steps = 10;
% 让我们从状态“T”开始,模拟系统进行num_steps步骤
current_state = "T";
for i = 1:num_steps
fprintf("Step %d: %s\n", i, current_state);
current_state = mc.rand(current_state);
end
```
这段代码创建了一个包含4个状态("T","W","D","L")的马尔科夫链对象,并定义了状态之间的转移概率矩阵。然后,通过循环模拟了系统进行了10步的状态转移,并输出每一步的当前状态。<em>1</em><em>2</em><em>3</em>
