以下是使用Matlab编写的动态规划逆序算法代码:
```matlab
function dpReverse(S, DecisFun, SubObjFun, TransFun, ObjFun)
\[m, n\] = size(S);
V = nan(m, n);
V(:, end) = ObjFun(S(:, end));
for k = n-1:-1:1
for i = 1:m
decisions = DecisFun(S(i, k));
subObj = nan(length(decisions), 1);
for j = 1:length(decisions)
subObj(j) = SubObjFun(S(i, k), decisions(j));
nextState = TransFun(S(i, k), decisions(j));
subObj(j) = subObj(j) + V(nextState, k+1);
end
V(i, k) = max(subObj);
end
end
disp(V);
end
```
这段代码实现了动态规划的逆序算法。其中,参数S是状态变量矩阵,DecisFun是允许决策集合函数,SubObjFun是阶段指标函数,TransFun是状态转移方程,ObjFun是第k阶段直到最后阶段的指标函数。算法首先初始化V矩阵,然后从倒数第二个阶段开始,逐个计算每个状态的最优值,最后输出结果。
希望这段代码能够帮助到你!
