Hi,
I'm trying to enter this into matlab: G(s) = 1/((C1+C2)s) How can I enter this into matlab? Thanks!

Hi
If C1 and C2 are constants you can simply use tf() function. If they are parameters using ode45 functions and a little code will help. Best

I can't seem to figure out how using the ode45 function will help me.
I have 4 equations: G1 = sym('1/((C1+C2)*s)') G2 = sym('C2*s') G3 = sym('1/(L2*s)') G4 = sym('1/((C3+C2)*s)') G5 = sym('1/(L4*s)') G6 = G2 % Set up equations V1 = ((V1) + (I2) + (V3)*G6 + Vin)*G1 I2 = ((V1) + (V3))*G3 V3 = ((I2) + (V1)*G2 + (Vout))*G4 Vout = ((V3) + (Vout))*G5 V1, I2, V3, Vout and I need to solve for Vout/Vin. How can I do this using Matlab? Thanks.

Matlab Transfer Function
Think I got it.
Used the solve function.
