Error in using classify function.

net=patternnet(10);

[net,tr]=train(net,trainoflow,op);

[ypred,scores]=classify(net,testoflow);

The above code give me error at classify function that Requires atleast three arguments. trainoflow is training features,testoflow is testdata features and op is train data labels.

net = trainNetwork(features,responses,layers,options)
