Change the interface of
bdalg.feedbackto that of Matlab'sfeedbackfunction. The current interface is too cumbersome for MIMO models.The function should react differently whether it has 2, 3, 4, or 5 arguments:
Implies: both systems may be MIMO or SISO; sys1.inputs == sys2.outputs; sys2.inputs == sys1.outputs
feedback(sys1, sys2)
feedback(sys1, sys2, sign)
Implies: sys1: MIMO; sys2: SISO
feedback(sys1, sys2, sys1_in, sys1_out)
feedback(sys1, sys2, sys1_in, sys1_out, sign)
See:
http://www.mathworks.com/help/toolbox/control/ref/feedback.html
The implementation should be no big intellectual endeavor, because a general implementation of feedback for MIMO systems already exists.
It just requires work, and a little design (maybe introduce a function
siso2mimo).The current implementation covers the case of 2, and 3 arguments.
