ss2tf does not work for MIMO systems #38

Closed baggepinnen closed 8 years ago

baggepinnen commented 8 years ago

it just returns a siso tf

nickquinnell commented 8 years ago

in general you cannot convert a state space model to a transfer function - should it return a matrix of tf's? Or should it return a tf in the SISO case and a matrix of tf's in all other cases?

All transfer functions are MIMO in the toolbox, there is no such thing as a siso transfer function exposed to the user. So a regular MIMO transfer function should be returned. On Mar 24, 2016 5:17 PM, "nickquinnell" notifications@github.com wrote:
