In Arduino IDE I use the following command: analogReadResolution(12). Does an equivalent one exist on Matlab?

As of now there is no equivalent from MATLAB support package for Arduino. Here is what I found out for Simulink https://www.mathworks.com/matlabcentral/answers/159964-arduino-due-and-simulink-voltage-resolution

Ok, thanks. So the only way is to write the code on Arduino IDE to have a better resolution. But If I want to read datas on matlab, it means that what I do on matlab is overwritten on the board?

Yes that is correct. When you work with the MATLAB Support package for Arduino, it downloads a new sketch that overwrites the current sketch on Arduino. You could try other workarounds like serial communication with MATLAB and Arduino having its own sketch, but they are all just workarounds.
