Set up MATLAB to work with RTL-SDR radios and third-party tools




sdrsetup modifies system PATH and LD_LIBRARY_PATH variables in the current MATLAB® session to use features in the RTL-SDR support package.

Run this command at the start of a new MATLAB session before using the RTL-SDR support package. You can automate this step for future sessions by adding sdrsetup to your startup.m file.

For instructions on creating or modifying a startup script, see the MATLAB documentation for Startup Options in MATLAB Startup File (MATLAB).
