I have a TF of H(s) and i dont know how to write code to plot it on matlab . We already solved it and i wanna use matlab to see if result are true. Can you help me please?

R= 10 k ohm.

L = 14.95 mH

C= 0.018013 pF

H(s) = R / ( R + Ls + (1 / Cs) ) = (R/L)s / ( s^2 + (R/L)s + 1/(LC) )

在 MATLAB Online 中打开

I would be tempted to use the Control System Toolbox —

R= 10; % k ohm.

L = 14.95; % mH

C= 0.018013; % pF

s = tf('s');

H(1) = R / ( R + L*s + (1 / C*s) )

H = 10 ------------ 70.47 s + 10 Continuous-time transfer function.

H(2) = (R/L)*s / ( s^2 + (R/L)*s + 1/(L*C) )

H = From input 1 to output: 10 ------------ 70.47 s + 10 From input 2 to output: 0.6689 s ---------------------- s^2 + 0.6689 s + 3.713 Continuous-time transfer function.
