Best Answer

>> [x,t] = simplefit_dataset;
[I N ] = size(x) % [ 1 94 ]
[O N ] = size(t) % [ 1 94 ]
% Instead of feedforwardnet, use fitnet for curvefitting or patternnet for classification.
net = fitnet;
MSE00 = mean(var(t',1)) % 8.3378
net.trainParam.goal = 0.01*MSE00;
[net tr] = train(net,x,t);
MSE = tr.perf(end) % 0.0202
NMSE = MSE/MSE00 % 0.0024
R2 = 1-NMSE % 0.9976 coefficient of determination (see Wikipedia)
Hope this helps.
Thank you for formally accepting my answer.
