I am a ham radio operator experimenting with RTL-SDR. What MATLAB products do I need and how much do they cost? I've purchased the book "Software Defined Radio using MATLAB and Simulink and the RTL_SDR." The author talks about needing MATLAB, Simulink (ver 2014b or newer), the Communications System Tool Box, The DSP Systems toolbox, the Signal processing toolbox and a RTL-SDR Hardware Support package. I didn't find these on the trial download site.
