Fuzzy logic toolbox - ANFIS - Calculate RMSE, MAE, R-squared

I am having 2 different data sets namely, training and testing.I need to calculate RMSE, MAE and R-Squared seperately for training and testing data. In the mathlab command window, I issue ANFISEDIT command. ANFIS editor window is opened. Training and testing datas are loaded in the "Load data" column. The FIS is generated with grid partition selected. The FIS is trained with Error tolerance =0 and Epochs = 3. Error value is displyed in the ANFIS editor window. Is this error is known as "RMSE" ? To test the FIS, I select the training data and Average testing error is obtained. Is this average testing error is known as "MAE"? While testing FIS with training data, Average testing error and error(training FIS) are same. While testing FIS with testing data, I obtain a different values for Average testing error and error. Kindly mention the procedure what I follow is correct.Plz help.
