please could anyone tell me if the system can be solved with the ode45 matlab?

It is an ordinary system.. I know all the constants, the variable are z,theta, phi and tau.

Another question.. How can I solve a system like this?

This is the way I have solved the system. Is it correct?

Thanks! Suppose I have the initial conditions. I solve the system in this way, tell me if it is write! I have a 3 dof system in heave, roll and pitch, of the second order. I call y=[ heave position, heave velocity, roll position, roll velocity, pitch position, pitch velocity]. I...

Hi! I have to solve the nonlinear equations of motion in the article (16) (17) (18). I Trasform the system in a system of first order differential equations but i don't have the initial conditions. Is it possible to solve it with the ode45 MATLAB function?
