How do I solve two different differential equations at the same time?
显示 更早的评论
I have a problem where I have to find the ideal rotation of a drum given many parameters. The solution has boiled down to too different ODEs.
where Fd_x is a 100x1 matrix and 
where Fd_y is also a 100x1 matrix. How would I go about solving this? Would I use ODE45? Thank you for your help.

hello
to do simple integration, you could start with cumtrapz to get the velocity data (from the force inputs)
the time vector is the same for both equations

I just realized that I forgot half of the equations so my bad. Would a simple integration still work if the other two equations are

sure, it's the same process with cumtrapz to integrate the velocity to get the displacement

hello
can you share the code + data ?
