Hi all, when any differential equations are in the form

y''=f(y,y',z,z'z'');

z''=f(z,z',y,y',y'');

'- represents the order of the derivatives

how to solve such equations using ODE solvers ?

That is too abstract to answer.

As with all the MATLAB ODE solvers, you have to create a system of first-order differential equations (‘companion matrix’) in your ODE function, then use that function as an argument to the ODE solver.
