title: Elman neural network Learn multiple-series series
body: <p>I start with neural networks, and I would like to know how I can do to have several input lists as an example of learning. In the documentation the example presented is the following :</p>
  
  <pre><code>[X,T] = simpleseries_dataset;
  net = elmannet(1:2,10);
  [Xs,Xi,Ai,Ts] = preparets(net,X,T);
  net = train(net,Xs,Ts,Xi,Ai);
  view(net)
  Y = net(Xs,Xi,Ai);
  perf = perform(net,Ts,Y)
  </code></pre>
  
  <p>where Xs and Ts are the input and the target, if i have serval series, should i repeat the learning for each series? thank you</p>
