PURPOSE

FEEDBACK Feedback connection of two input/output fractional-order transfer functions.

SYNOPSIS

function G=feedback(F,H)

DESCRIPTION

 FEEDBACK Feedback connection of two input/output fractional-order transfer functions. 

    M = feedback(G,H) computes a closed-loop model C for the feedback loop:

          u --->O---->[ G ]---------> y
                ^               |
                |               |
                ------[ H ]<-----

    Note, that fractional-order systems in the feedback loop must have
    equal delays or lack thereof.
