Does anybody know if Mathematica has an analogue of MATLAB's
ode45 command? I need to solve a second order coupled ODE system of equations.
According to the Mathematica documentation on this page:
is the second order ODE specified in the usual Mathematica manner for ODE's.

And a simple example (modelling coupled springs with added nonlinear restoring forces (for large vibrations)):
