sorry, function "[T,Y] = ode45(@StateSpaceForm, Time, IC, SolverOptions, m, d, c, f);" is not working. why ?

Is your function even called StateSpaceForm? Also name the file for the function the same!

Great stuff, please do a quarter car and half car model. it would be amazing to find out using an if statement can you for loop and find the correct damping for a critically damped system.

Thanks for the video, first time I managed to create such a thing in Matlab. But how can I create a sine wave as force input, so that f=sin(t) for example?

Thanks mate! Yes I do but the potential of being banned is quite high, got banned in 2 subreddits. If I were you I would give it a try in the ML/DL/RL subreddits. I will give a shoutout to your channel once I have the time to create a beginner‘s guide to machine learning/RL! Or you create one beforehand yourself 🙂😉

thanku very much for your videos , if mass matrix is having 2x2 size, how can apply this code?? can u pls explain this
@JousefM3 жыл бұрын
Just give it a try with 2x2 and see what error it throws. Always use the workspace to see what dimensions you’re working with and if these even make sense. „Debugging“ using the workspace is very helpful sometimes.

Nice work!!! In the case of a harmonic displacement for the same mass-spring-damper SDOF model where the goal would be to find the generated force due to the harmonic displacement. Do you have some recommendations to carry out such a case?

I have a similar question to this one, however, I need to find the force (force * acceleration), so I need to find the acceleration of the mass, how would I be able to do it?

You can plot and calculate the acceleration as shown in the video. If you only have the velocity take the derivative

Hey Malik! The mass was included as the small parameter m but not gravity as you might have seen. But you could include it of course - the equation would look slightly different :)
