I have a small question!
If I have a transfer function matrix $G(s) $ and want to plot all singular values, like a bode plot, except for the phase part. Can I just find the frequency gain and then use SVD in Octave/MATLAB to plot every dot ?
For example $G (0) $ will give me the low frequency gain. In this case it will be a matrix of real numbers. I use $svd (G(0)) = U S V^T$ and get the singular values matrix $S $. Store from $S $ into a vector and then use the next frequency $s $ for the transfer function.
Or do I need to use $j\omega $ insted of $s $?
Is that correct?
