Hi friends,(adsbygoogle = window.adsbygoogle || []).push({});

I have a system (with unknown properties) which takes an input vector of length 10 and outputs a vector with length 6.

I select Inputs vector 'I' which is a 1000x10 matrix, : 1000 samples of 10 elements. And outputs vector 'O' is a 1000x6 matrix,: 1000 samples of 6 elements.

I just want to find input output relation ie system identification.

How can I do this using neural network toolbox in matlab?
