MATLAB: How to calculate the error in Neural Network Back Propagation Network

Use as many defaults as possible

 MSEgoal = 0.01*mean(var(target',1))
 MinGrad = MSEgoal/100
 net = newff(input,target);
 net.trainParam.goal     = MSEgoal;
 net.trainParam.min_grad = MinGrad;
 [ net tr output error ] = train(net, input, target);

For details, search ANSWERS using the search word msegoal
