I am playing around with the built-in bandwidth function.
I can intuitively understand what is going on under the hood for a transfer function with scalar input and scalar output. However, how is the band width computed when the input is a vector of length > 1?
For instance, as in this example from the documentation:
A = [-2 -1; 1 0];
B = [1; 0];
C = [1 2];
D = 1;
sys = ss(A,B,C,D);
