How to use the already trained neural network

I recently used Neural Network toolbox from Matlab to train a neural network for detecting violence in movies. After training the network and obtaining a good performance I've been searching for the function that let me use the network and I can't find it. Can you help me on using the network after training it?

PS: I just want to try the network giving one input and getting an output

Dude, can I ask a question not related to this. How did you get the network or your script to read the screen, let alone detect violence for your data. What I need specifically is to open up a game saved on my desktop and let my neural network train on it, could you please help?

y = net(x)

where net is your trained network and x is your new input.

I tried that but when I do so, I was expeting a 2x1 matrix with the output for each class but instead I receive a 2x36 matrix where 36 is exacly the same number of each input attributes.

Can you show me a code example, inputs and outputs where that works out?

Better yet, what are the sizes of the matrices you used for training

 [ I N ] = size(input)
 [ O N ] = size(target)

Then, for each I-dimensional column input test vector, x, you should get an O-dimensional column output vector y.

I did it! I had to traspose one of the matrixes! Thanks man
