Re: [Discuss-gnuradio] how to save the usrp samples to a file sink ?

[Marcus Müller]

Probably because you did not read the file in matlab in a manner that
tells Matlab it's complex, so matlab maybe defaulted to int? I don't know.

There's a convenience script that comes with GNU Radio that you can use
in Matlab to read the binary files[1].

Best regards,
Marcus
