Convert transfer function from state-space to zero-pole form.
Convert a transfer function defined in state space presentation of the real valued A matrix, B,C vectors and D value. in to its zero-pole form with zeros Z, poles P and gain K. State space system is related to its numerator/denominator representation via the following relation:
num(s) (s-sz1)*...*(s-szn) H(s) = -------- = K*------------------- =C*(s*I-A)^(-1)*B + D den(s) (s-sp1)*...*(s-spn) dx/dt = Ax + Bu y = Cx + Du x - system input y - system output szn - n'th zero spn - n'th pole K - system gain
