Hi All,
RTL-SDR support package for MATLAB and Simulink has been released:
http://www.mathworks.com/hardware-support/rtl-sdr.html
Using this support package, you can receive signals from your RTL-SDR dongle directly into MATLAB and Simulink. The package also contains several examples to get you started.
Have fun and let me know if you have any questions or comments.
