Pablo, If you are working in Matlab, it is possible to use your SDR natively assuming you have the proper licenses. There's a good (Free!) guided textbook here: http://www.desktopsdr.com/ and the Mathworks support package can be downloaded here: https://www.mathworks.com/hardware-support/rtl-sdr.html
Personally I use both Matlab and GNU Radio depending on the task at hand.
