How can I pass Matlab simulation data to Unreal Engine model?

At the moment I'm looking for a way to pass data from Matlab to Uneal Engine. I have a whole numerical model of a system in matlab&simulink and create data of the movements of the body (like a time-distance table). Now I want to visualize the computed behaviour of the matlab model with the visual model in Unreal Engine. Does someone know something about similar applications, tutorials, documentations oder videos that could help me with my question? i would be very thankful for any answers!

Jakob, I am looking at doing something similar I would love to communicate on this so we can quickly come to a solution. I am currently working on a research project where I am building a flight sim using a physics model in matlab and looking to integrate that with UE4 to drive the physics while UE4 handles the visuals.

Maybe you can use the MATLAB API for C++: https://fr.mathworks.com/help/matlab/Cpp-api.html https://fr.mathworks.com/solutions/matlab-and-other-programming-languages.html#converting_matlab_code_to_c_code

I've never done it but I intend to try it

@Preston Webb, did you manage to get a solution for this?

Dear Jakob,

Starting in R2024B, you can use the Read UAV Trajectory block to generate translation and rotation samples from a UAV trajectory that you create using a multirotorFlightTrajectory, fixedwingFlightTrajectory, polynomialTrajectory, or waypointTrajectory object in MATLAB.

You can then use the output of this block as an input for the Simulation 3D UAV Vehicle block to place the UAV in the Unreal Engine scenario.

Please refer to these examples for more information:
