MATLAB does not seem to have any built-in support for GR. So possibly the best way is first to obtain the system of equations from another system that does have GR support and export it to MATLAB. For example here is SageManifolds notebook for geodesics in Schwarzschild metric, An ODE system ready to export is after the line sys = geod.system(verbose=True).

| Jun 2, 2019 at 7:26 | comment | added | almost | @Avantgarde thx for your reply. I don't want to use mathematica at first. I startet to implement the ode in Matlab and solved it with standard ode-solver. I'm curious to know how the constant of motions and intial conditions are set up. | |
