Second Order Coupled Differential Equations
显示 更早的评论
Is it possible to write code to model this type of differential equation? :
x'' = f(y, y', y'')
y'' = g(x, x', x'')
Thanks!

Yes, MATLAB has several different functions for solving ODEs. The video and documentation page I linked in my answer describe how to use some of them, and the page I linked in this comment includes another example and offers some guidance about which solver to use for particular types of problems.

Can you solve for x'' and y'' , i.e.
x''=function1(x,x',y,y') y''=function2(x,x',y,y')
?
If yes, you can use any ODE solver from the ODE-suite you like.
If not, try ODE15i.
Best wishes
Torsten.
