Problem Definition

Here is the definition of a signal T, which lasts 5 seconds, and is defined at a sampling rate of 40 samples per second.

• time = 0:0.025:5;
  T = sin(time*4*pi);
  Q = length(T);
  

At any given time step, the network is given the last five values of the signal t, and expected to give the next value. The inputs P are found by delaying the signal T from one to five time steps.

• P = zeros(5,Q);
  P(1,2:Q) = T(1,1:(Q-1));
  P(2,3:Q) = T(1,1:(Q-2));
  P(3,4:Q) = T(1,1:(Q-3));
  P(4,5:Q) = T(1,1:(Q-4));
  P(5,6:Q) = T(1,1:(Q-5));
  

Here is a plot of the signal T.
