How can I change the resolution of ''Arduino 2'' from 10 to 12 bit using Matlab?

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

Thanks for your answer! How can I use Simulink S-function in my MatLAB code?

[Madhu Govindarajan]

Unfortunately, it is not possible to use Simulink S-function with MATLAB code. It can only be used with Simulink. I will pass this request along to the developers, so that they can consider implementing this feature in a future release.

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?

[Madhu Govindarajan]

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.
