Hello,
I am wondering what happens exactly when I multiply 2 state spaces?
Such that systemA = ss(A,B,C,D) and systemB = ss(AB,BB,CB,DB) and then systemA*systemB. I would like to use it in code generation but the ss() function is not supported, which is why I need to understand how the multiplication of the 2 state spaces work.

The multiplication operator (*) is the same as a series call. It appears to connect the outputs of one ‘sys’ object to the input of another, so that is likely how it would be implemented. The documentation says nothing about how the function works beyond that, however.
