Hello, im trying to plot this transfer function but somehow i dont know exactly what is failing, here is what im trying:
syms s
D=[2+s^2 -1 0;-1 s^2+2+s*0.5*10/(s+10) -1;0 -1 2+s^2];
H=inv(D);
H11r=H(1,1)
H22r=H(2,2)
H33r=H(3,3)
s=0:0.01:5;
plot(s,H11r)

Please explain in a bit more detail what you want to do.
I do not understand ‘H’. What are you doing?
Do you have the Control System Toolbox?

If you have a somewhat recent MATLAB, then instead of using
s=0:0.01:5;
plot(s,H11r)
instead use
fplot(H11r, [0 5])
Otherwise:
s=0:0.01:5;
plot(s, subs(H11r))
