How to use "nprtool" for testing multiple data ?

dear sir,

i am using neural classification tool "nprtool". i have 500 training data and using that once the network is trained i want to test four different data sets for the same training.

i have gone through the webnire of nprtool, i could understand how to use it. but couldnt undersatnd how to test multiple data with same trained network.

i am new to neural networks. please help me for the same.

hello chirag

i used 500 samples to train nprtool with 4 features, category 1 have code [0;1] and category 2 have code [1;0];

after training i randomly take a sample having 4 features and fed to trained NN. if NN outputs are [0;1] it belongs to category 1 otherwise at [1;0] category 2.

%////////// nn training //////////////////////////////

inputs=randint(4,500,[1 10]);
outputs=randint(2,500,[0 1]);

hiddenLayerSize = 10;
net = patternnet(hiddenLayerSize);

net.divideParam.trainRatio = 70/100;
net.divideParam.valRatio = 15/100;
net.divideParam.testRatio = 15/100;

[net,tr] = trainrp(net,inputs,outputs);

%///////////////// nn testing //////////////////////////

input=[2;3;5;6];
nn_output=round(net(input));

if(nn_output==[0;1])
    display('category 1');
end
if(nn_output==[1;0])
    display('category 2');
end
