Hello,
I have the following question: I want to calculate the MAE and RMSE in percentage. The following code gives the correct result?
MAE_Perc=mae(True-Predict/.True);
RMSE_Perc=sqrt(mse(Tru-Predict)/.True);

MAE_Perc=mae((True-Predict)/.True); % <-- bracket needed here
RMSE_Perc=sqrt(mse(Tru-Predict)/.True);

RMSE_Perc=sqrt(mse(Tru-Predict)/.True); %<-- That "dot" after the division slash is wrong
And if we change to "./", the result in a vector.
So, how to obtain just on value representing the RMSE%?
