MATLAB How can i train NARX neural network with multi dataset

Question

I create NARX network for 16 input and 1 output like this

in=[u1(1) u1(2) ... u1(t)
    u2(1) u2(2) ... u2(t)
      .     .         .
    u16(1) u16(2) ... u16(t)];

target=[1 2 ... t];

and i want to train with 5 dataset of input and output, but i don't know how to create the one input and target matrix with 5 dataset to train NARX.

Answer 1

You can combine datasets with

catsamples()

For example:

X = catsamples(x1, x2,..., xn)
T = catsamples(t1, t2,..., tn)

The optional parameter 'pad' allows concatenating datasets with varying sizes.

For further informations take a look at catsamples in the MathWorks documentation.
