MAE and RMSE in percentage

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);

Answer 1

[KSSV]

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

[WELTON DUQUE]

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%?
