title: How to feed with 2 or more inputs a Neural Network in Matlab
body: <p>I want to feed a Neural Network with more than one input (using the Matlab tool Box). </p>
  
  <p>If I declare the input vector like <code>P = [1 2 3 4; 1 2 3 4; 1 2 3 4;1 2 3 4]</code>, the target as <code>T = [1 2 3 4]</code> and then the network as <code>net = newff(P,T,1);</code>, when I look at the network parameters it says <code>numInputs: 1</code>, while in my mind the number of inputs should be 3 (one for each row). </p>
  
  <p>My question is: how to feed the network with 3 separated inputs?</p>
  
  <p>Thanks in advance,
  Regards
