ME 340: Example, Solving ODEs using MATLAB's ode45 command

[brynmrsh]

This is great. Now I can solve my homework problem. My school thinks that we become great engineers by being taught nothing, but being forced to use specific solution techniques, such as ode45, to solve problems that we have no idea how to even work out on paper. Thankfully, there are great schools which put examples on YouTube.

I wish I stumbled on this video sooner. My professor expected us to know matlab without ever being taught it. I might just make it with this guide now

Thank you so much. I love you motto ' Learn by doing', with a simple example, you helped many of us understand what our teachers wasn't able (willing in my case) to explain.

Finally, Thank you so much for this video. Ive been sitting for hours following instruction from my textbook with a bunch of errors.

[VDEngineering]

Could you please do a tutorial where the function has extra parameters which are time dependant?

For example, the 6-DOF equations of motion have coefficients which change depending on the pitch angle and so on.

May God reward you for all your effort and all the valuable information you easily provide to us .

Great video, the first I watch learning about state-space presentation of ode. I followed the slides religiously and there is probably an error at 2:22. Last line: The first quantity (a_n-a/a_n) on the right-hand side of the equation should be multiplied by x_n and not x_n-1?

ODE I wanna cry Industrial Engineering TT

Very well explained sir! Thank you very much! :) :)

[LL-knde]

Thank you! This really helps! Can you do a 2nd order d.e relate with RLC circuit problem?

[crosser]

Thank You. You made my day. I've got errors that odearguments must return a column vector. Transposition at the end of function solved the problem. Thank you very much :D :D :D :D :D

Thanks K-J! you helped us greatly, from sweden with kisses xxxo

what is the meaning of (:, 1) after the x in the plot function?

How can I plot y''-xy=0 with initial conditions y(0)=1, y'(0)=1 ?

[alemayehuwakjira]

Dear sir thank you for your lecture on using ode45 for state variable solutions. my question is, is the name func a predefined name that can not be changed to other name? should I necessarily replace every time I save my file with same name func?

[seanlin]

excuse me, if I solve nonhomogeneous ODEs, Do I need to convert r(x1) into yp obtained by the modification rule? and if I use this method, how to define C, Kcos, Msin.
Or should I just add r(x1) directly like this:

[ghufransyed]

thank for this video, really helped me understand how to use the matlab ode function!

[stressedbyamountainofbooks]

How do you do this if the known value for xdot is when t=10, this is not initial value

[DhruvPatel-jfgg]

ultimately we are finding x right??...How Matlab going to find it from xdot=[xdot1, xdot2] values?...please guide me!!

[vipulkumar]

at 2:22. shouldn't there be xn instead of xn-1 with (-an-1/an). talking about first expression on the RHS.
