matlab实现MAE

要在MATLAB中实现MAE（平均绝对误差），你可以使用以下示例代码：

function mae = calcMAE(predicted, actual)
    absoluteError = abs(predicted - actual);
    mae = mean(absoluteError);
end

这个函数`calcMAE`接受两个参数：`predicted`是模型的预测值，`actual`是真实值。它首先计算预测值与真实值之间的绝对误差，然后取平均值作为MAE。你可以将该函数嵌入到你的MATLAB程序中，以计算MAE并评估模型的预测效果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
