Code can only be deployed to the LEGO EV3 Brick using Simulink. With the MATLAB Support Package, you can communicate with the LEGO EV3 Brick using MATLAB scripts. However, you cannot deploy a MATLAB script such that it is a stand-alone program.
Much of MATLAB’s functionality can be implemented in Simulink. The suggested workaround would be to model the desired functionality in Simulink instead. This can be done by either using the blocks provided by Simulink or by using a MATLAB function block in your Simulink model.
Note that if you choose to use a MATLAB function block, ensure you are only using functions that are supported for code generation. To see a list of functions that are supported for code generation, see the following documentation link:
