Neural Network Toolbox

Problem Definition

The following code defines two sine wave forms, one with an amplitude of 1.0, the other with an amplitude of 2.0.

• p1 = sin(1:20);
  p2 = sin(1:20)*2;
  

The target outputs for these wave forms is their amplitudes.

• t1 = ones(1,20);
  t2 = ones(1,20)*2;
  

These wave forms can be combined into a sequence where each wave form occurs twice. These longer wave forms are used to train the Elman network.

• p = [p1 p2 p1 p2];
  t = [t1 t2 t1 t2];
  

We want the inputs and targets to be considered a sequence, so we need to make the conversion from the matrix format.

• Pseq = con2seq(p);
  Tseq = con2seq(t);
