matlab求mae的函数

function mae = calcMAE(actual, predicted)
% This function calculates the mean absolute error (MAE) given the actual and predicted values.
% Inputs:
% actual: a vector of actual values
% predicted: a vector of predicted values
% Output:
% mae: the mean absolute error

error = abs(actual - predicted); % Calculate the absolute error
mae = mean(error); % Calculate the mean of the absolute error
