Think I got it. Used the solve function.

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) +...

Hi, I'm trying to find the transfer function to this circuit (see attached image). I put together a MATLAB script file which I will paste the code below. I found the transfer function to be...

Thanks for the response Berkeman. I think you might be right. Could you show a quick example of how I can proceed using matlab? I was thinking of using the sym function but I've also been told that I could use ode45 functions (although I'm not familiar with ode45 functions). Thanks.

Hi, I'm having some trouble reducing a leapfrog block diagram shown in the attachment. I want to find the transfer function but I don't know how to reduce the portions which "leapfrog". I can reduce the feedback loops G1 and G4 but not too sure on where to go from there. Any help is...

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