If you use MATLAB Support Package for Arduino, there is readRegister function to read data in - https://www.mathworks.com/help/supportpkg/arduinoio/ref/readregister.html
The caveat here is you must know the right commands to write to the register so that you can put the sensor in default send data mode. You should be able to find this from the sensor spec sheet or existing Arduino code. If you need assistance with that, post the Arduino sketches here and some one should be able to assist you.
