I have a MIMO system with a 2x2 transfer matrix, for example consider:
$\begin{pmatrix} \frac{2}{s+1} & \frac{1}{(s+1)(s+2)}\\ \frac{1}{(s+1)(s+2)}&\frac{2}{s+2} \end{pmatrix}$
I would like to know how to characterize the influence that each channel has on another channel using Matlab.
So I would like characterize the effect of the coupling between the channels.
I know that to see how much a channel influences another i could use RGA, but is there also a way to see this by looking at the step responses and the magnitudes of the frequency responses?
Thank's in advance.
