Neural network tool application

When I use Neural network tool, I don't know how can I apply trained model. After I made a network file, how can I apply the model to new input data?

Hi Gaeul,

As I understand you would like to test the Neural Network for new inputs(testing data). You can use the 'net' function to test the network. Please take a look at the following code snippet:

% Create a Pattern Recognition Network
hiddenLayerSize = 10;
net = patternnet(hiddenLayerSize);

% Train the Network
[net,tr] = train(net,inputs,targets);

% Test the Network
outputs = net(inputs);
errors = gsubtract(targets,outputs);
performance = perform(net,targets,outputs)

The example given above assumes a Pattern Classification Neural Network in use.If your application involves fitting data with NN please refer to the following link:
