Take a look at the "Methods" section under
https://en.wikipedia.org/wiki/Numerical_methods_for_ordinary_differential_equations

Any function in matlab that can do the conversion?

If you use one of the ODE-integrators under
https://de.mathworks.com/help/matlab/ref/ode45.html
the conversion method is already integrated.
If you want to write your own ODE solver, you will have to implement the method on your own.
