Hi there..... i used following code to train network .

Opts = detectImportOptions('annn.txt'); Data = readtable('annn.txt', Opts);

input = {'T', 'Wdi', 'S', 'R','W'}; i = Data(:, input);

p=table2array(i); % inputs are converted in to arraycell

respone=Data.kWm % target response

% net=feedforwardnet([n m]); n no of neurons in the first hidden layer AND m no of neurons in second hidden layer

net=feedforwardnet([5 10]); net.trainparam.epochs=14 %epoch net = configure(net, p', respone')

[net, info] = train(net, p',respone');

 now i want to calculte the train and test mean square error MSE. by using formula can anybody help me please/ see attachment datafile
