Take a look at the "Methods" section under

Any function in matlab that can do the conversion?

[Torsten]

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.
