帮我写一份演化博弈的MATLAB代码

好的，下面是一份简单的演化博弈的 MATLAB 代码：

% 定义每一步操作的获益
T = 1;
R = 3;
P = 0;
S = 5;

% 定义每个人的初始策略
strategy = [0.5, 0.5];

% 定义博弈的次数
n = 1000;

% 开始博弈
for i = 1:n
    % 随机决策
    decision = rand(1, 2) < strategy;
    
    % 定义每种决策的获益
    payout = zeros(1, 2);
    payout(decision == [1, 1]) = R;
    payout(decision == [1, 0]) = S;
    payout(decision == [0, 1]) = T;
    payout(decision == [0, 0]) = P;
    
    % 计算策略的改变
    strategy = strategy + (rand(1, 2) - 0.5) * 0.1 .* (payout - mean(payout)) / std(payout);
    
    % 限制策略的范围在 0 到 1 之间
    strategy = max(0, min(1, strategy));
