pole-placement design

This function can be used for measuring the parameters of forward path gain and the feedback gain for a pole-placement controller design

[F G]=dio(A,B,Am)

if
f*a g*b=am

a=1 (a1)*z^-1 (a2)*z^-2 .... (an)*z^-n
b=(b0) (b1)*z^-1 (b2)*z^-2 .... (bm)*z^-m
am=(am0) (am1)*z^-1 ... (amr)*z^-r
f=(f0) (f1)*z^-1 ... (fp)*z^-p
g=(g0) (g1)*z^-1 ... (gq)*z^-q

then
A=[1 a1 ... an]
B=[b0 b1 ... bn]
Am=[am0 am1 ... amr]
F=[f0 f1 ... fp]
G=[g0 g1 ... gp]
