idnlhw command (Hammerstein-Wiener model) for MIMO system? How to set Orders and B and F matrixes for MIMO system?

Hi Everyone,

I'm trying to use idnlhw command (Hammerstein-Wiener model). For SISO system it's clear that how to set B and F. But my system is MIMO; for example, for a system with 3 inputs and 2 outputs I need B as a cell array of 2-by-3 elements. According to matlab help an element B{i,j} is a row vector representing the numerator polynomial for the jth input to ith output transfer function. Is there any way to set B in this way?

Thank you

For the ith output of the jth input, if the polynomial vector is for eg.- pij=[1 2 3], you can define the B like

B={p11 p12 p13;p21 p22 p23};

For a MIMO system with 2 outputs and 3 inputs.

Hope I understood you correctly.
